Hi all,
We are working on a SH 7705 processor based board.
The linux kernel we are using is 2.6.16 with SH linux stable patch (sh--stable--2.6.16). At the moment the linux kernel
is running well with basic features. We're getting following problem with flash file system (JFFS2).
We have two flash partitions on our system and can be mounted using JFFS2.
Once partitions are mounted we can do standard file system operations like create/remove directories, files.
But when we try to copy a directory, it copies the files inside the directory and at the end the system crashes
with following errors. Further more copying individual file, one by one doesn't make any problem.

---------------------------------------------------------------------
We're using Solution Engine as the target board and modified the linux-2.6.16.9/drivers/mtd/maps/solutionengine.c file
according to our needs. Flash memory type is Spansion (MirrorBit family) S29GLxxxN.
If any one knows why this happnes and give us some thoughts on this, it will be a great help.
Thank you in advance

SH7705 doesn't work in the latest kernel.
I am grappling with this problem. ( not your jffs2 issue )
Please wait for a while.

Nobuhiro.

Hi Nobuhiro and Paul, First of all thanks for adding support for SH7705 in the latest kernel. With the sh: Solution Engine SH7705 board and CPU updates (http://git.kernel.org/?p=linux/kernel/git/lethal/sh-2.6.git;a=commit;h=5452d25e28f365938b36f3a972fe2a1bb69a4c3e) added by Nobuhiro Iwamatsu to the sh-2.6.git and some other additional modifications, I managed to successfully run the 2.6.20.7 kernel on SH7705. In addition to the above modifications added by Nobuhiro, following additional modification was needed. As I found that the file arch/sh/kernel/cpu/sh3/entry.S is broken for SH3 in 2.6.20.7 kernel. arch/sh/kernel/cpu/sh3/entry.S ... ... #if defined(CONFIG_CPU_SH4) #define ldmmupteh(r) mov.l 8f, r #else #define ldmmupteh(r) mov #MMU_PTEH, r #endif ... ... here for the SH3 (when CONFIG_CPU_SH4 is not defined), the ldmmupteh(r) is defined as "mov #MMU_PTEH, r". At this line the compiler throws the error - "value of 00000000fffffff0 too large for field of 2 bytes at ...". The error is due to that line attempts to load a long word value as an immediate data and it can be fixed by changing it some thing similar to "mov.l 8f, r" and it works for me. Please let me know if I'm wrong with this. Further more, in my system the Default bootloader kernel arguments is "mem=32M console=ttySC0,115200 root=/dev/ram". After the above modifications, the kernel uses SCIF2 as the console output, but SCIF2 should be selected only if console=ttySC1 is used... isn't it ? I guess this is because of the modifications done to arch/sh/kernel/cpu/sh3/setup-sh7705.c Please correct me if my argument is wrong. Still I couldn't verify the JFFS2 problem (I was experiencing with 2.6.16.9) is fixed or not in 2.6.20.7 kernel. I'm looking forward to find it out, and I'll keep posting any more useful findings. Thanks again.

Hi all, I'm using linux kernel 2.6.21-rc7 with the sh: Solution Engine SH7705 board and CPU updates (http://git.kernel.org/?p=linux/kernel/git/lethal/sh-2.6.git;a=commit;h=5452d25e28f365938b36f3a972fe2a1bb69a4c3e) added by Nobuhiro Iwamatsu to the sh-2.6.git. Initial boot up of the kernel works fine, I'm getting the early console outputs, printk is working, but after the ram disk is mounted and when the init/main.c starts the /sbin/init, I'm not getting the system console. This ram disk with the busybox ver 1.00 was working fine with 2.6.16.9 kernel (with sh--stable--2.6.16 patch). To find out the problem, I replaced the /sbin/init with a small helloworld program (dynamically linked) which has only a printf in a loop, then I noticed that the printf is not working. This program was also working fine with 2.6.16.9 kernel (with sh--stable--2.6.16 patch). As a summary, my situation is the system boots up fine, printk is working fine but printf is not working and also busybox is not able start a console. This might appear like a crazy question, but if any one have some idea about this, it will be a great help. Following is the early console output of my system. ------------------------------------------------------------------------------- Linux version 2.6.21-rc7 (root@cmmnml-linux-vm) (gcc version 3.4.4) #5 PREEMPT Thu Apr 26 14:58:55 LKT 2007 Built 1 zonelists.

In my environment (NFSboot), the console of busybox is working .
Could you send your Carnelconfig?

Hi Nobuhiro and Paul,
First of all thanks for the reply.
I was using 32KB cache option, but removing that option didn't solve the problem. Following is the content of my configuration file (.config file). If I have missed any thing here, and if any one can show me the correct path, that will be a great help.

Hi all,
I tried with turning off the CONFIG_SH_DSP option, but didn't solve the problem.
Further more to find out more about the problem, I did following hack and got some information which might be useful to identify where the real problem is.
( 1 ). I put a printk inside the "static irqreturn_t tmu_timer_interrupt(int irq, void *dummy)" function in arch/sh/kernel/timers/timer-tmu.c file like below.
...
...
/*
* Here we are in the timer irq handler. We just have irqs locally
* disabled but we don't know if the timer_bh is running on the other
* CPU. We need to avoid to SMP race with it. NOTE: we don' t need
* the irq version of write_lock because as just said we have irq
* locally disabled. -arca
*/
printk("Cmmn\n");
write_seqlock(&xtime_lock);
...
...
( 2 ). Replaced the /sbin/init with a statically linked executable which has only a while loop as below.
#include <stdio.h>
int main()
{
while(1)
{
// do nothing
}
return 0;
}
( 3 ). Put printk messages at the end of the init_post() function in init/main.c file as below.
...
...
printk("Debug: calling /sbin/init\n");
run_init_process("/sbin/init");
printk("Debug: calling /etc/init\n");
...
...
I tested this with both 2.6.16.9 (with sh--stable--2.6.16--base-0 patch) and 2.6.21-rc7 (with sh: Solution Engine SH7705 board and CPU updates (http://git.kernel.org/?p=linux/kernel/git/lethal/sh-2.6.git;a=commit;h=5452d25e28f365938b36f3a972fe2a1bb69a4c3e) added by Nobuhiro Iwamatsu to the sh-2.6.git) kernels. As expected for 2.6.16.9 kernel I'm getting the printk message continuously for each timer interrupt, but for 2.6.20-rc7 kernel, after the run_init_process("/sbin/init") function is called, I'm not getting the printk messages from timer interrupt. In other words once it tries to start the sbin/init process, the kernel hangs itself and even timer interrupt is not handled. So this means that the kernel fails to start a user space process and puts it self to a not running state.
According to above observation, I doubt this may be due a problem in the area where the kernel tries to start a user space process. Can it be a possibility ? If any one can give me some thoughts, it will be a great help.
Thank you

Hi all,
Thanks for replying on this matter. Still I couldn't solve the problem with 2.6.21-rc7 with SH7705.
I changed my system to LITTLE ENDIAN also, but the same thing happens.
As a summary what happens is the kernel boots up fine up to the point where run_init_process("/sbin/init") is called. After the run_init_process("/sbin/init") function is called, kernel hangs itself and even the timer interrupt is not handled. As I feel the kernel fails to start a user space process and puts it self to a not running state.
According to above observation, I doubt this may be due a problem in the area where the kernel tries to start a user space process. Can it be a possibility ? If any one have used 2.6.21-rc7 on SH7705 successfully and any one can give me some thoughts, it will be a great .. great help.
By the way, I' trying to use 2.6.21-rc7 is mainly because of the JFFS2 file system problem I experienced with 2.6.16.9 kernel (in 2.6.16.9 kernel, trying to copy a directory which is larger than around 2 MB makes the system to crash). If any one have experience that problem or have any idea about it, that will also be a help for me to sort out this problem.
Thanks

Sorry , I dont check bigendian.
I checked little endian only.

If you're never getting the timer interrupt, then there's certainly
something terribly wrong with the IRQ handling. That has to be fixed
first.
These should already be handled via the IPR map though, are you dealing
with a custom board? Do you have any unusual TMU configuration? Also make
sure that the timer IRQ is set to the proper vector.. You need to be
getting interrupts before you start worrying about userspace problems.
Your config looks pretty close to the SE7705 defconfig, so the timer
should certainly not be causing you any difficulty.

Hi Paul, Thanks for the reply, as I'm still in the process of getting the problem fixed. Let me allow to brief you about the problem I'm having. As you have mentioned about my configuration file, it is based on SE7705 defconfig file. The board I'm working on is virtually the same as the Solution Engine board. On this board 2.6.16.9 kernel (with sh--stable--2.6.16--base-0 patch) is running well without any problem other than a problem I was experiencing with JFFS2 file system (trying to copy a directory which is larger than around 2 MB makes the system to crash). Because of that I'm trying to use 2.6.21-rc7 kernel to see whether the JFFS2 problem is fixed in it. To build the 2.6.21-rc7 kernel for SH7705, I had to add a patch from 2.6-git added by Nobuhiro (http://git.kernel.org/?p=linux/kernel/git/lethal/sh-2.6.git;a=commit;h=5452d25e28f365938b36f3a972fe2a1bb69a4c3e). This patched 2.6.21-rc7 kernel boots up fine, but fails to start the /sbin/init and stops running. To check at least the timer interrupt is handled after this point, I added a printk into the timer interrupt handler. With this, when the kernel boots up, after the timer interrupt is registered, I'm getting the printk messages for each timer interrupt as expected. As you suggested that makes me sure that the timer IRQ has no problem. But at the end of the initial kernel bootup process, when it tries to start the system console by calling run_init_process("/sbin/init"), everything goes wrong. As I mentioned, after calling run_init_process("/sbin/init") function, the kernel hangs at that point and there after I'm not getting the printk message from the timer interrupt handler. That means after this point, the kernel is not in a running state. Based on all the above observations, I suspect that we may have a problem in the kernel where it tries to start the /sbin/init. I'm wondering to know that can it be a possibility that there may be a problem in the kernel when it tries to start /sbin/init ? if so where should I look to fix it up, and is there any one who has successfully used the 2.6.21-rc7 kernel on SH7705 without this problem ? If any one of you can give me some thoughts about this, that will be a great help for me to fix it up. Thanks in advance.

If you have an sh4, then there's also a well tested gcc 4.1 toolchain and the standard user-space apps and libraries packages in RPM format (srpms also available) at http://www.stlinux.com/pub/stlinux/2.3ear/STLinux/ There is also the beta uClibc with NPTL threads for sh4 and glibc 2.5 Paul's been working hard recently to push the sh kernel changes into mainline. There is also the sh kernel GIT development trees at http://git.kernel.org (look for the linux/kernel/git/lethal/* projects).
