I'm running into a problem where the GPIO values I set in u-boot seem to be getting overwritten when the Linux Kernel boots up. However, I need these GPIO values to be persistent until my program changes them. How I am setting the GPIO values via u-boot: I'm using GPIO pins 17-20 so first I modified "/psp/u-boot/board/overo/overo.h" to set all the pins to mode 4 (I'm NOT using an extra SD card so it should be fine to use these pins for GPIOs): MUX_VAL(CP(ETK_D3_ES2), (IEN | PTU | EN | M4)) /*MMC3_DAT3*/\ MUX_VAL(CP(ETK_D4_ES2), (IEN | PTU | EN | M4)) /*MMC3_DAT0*/\ MUX_VAL(CP(ETK_D5_ES2), (IEN | PTU | EN | M4)) /*MMC3_DAT1*/\ MUX_VAL(CP(ETK_D6_ES2), (IEN | PTU | EN | M4)) /*MMC3_DAT2*/\ Next, I went into "/psp/u-boot/board/overo/overo.c" to actually set the GPIO values: omap_set_gpio_direction(17, 0); omap_set_gpio_dataout(17, 0); printf("17: = %d\n", omap_get_gpio_datain(17)); omap_set_gpio_direction(18, 0); omap_set_gpio_dataout(18, 1); printf("18: = %d\n", omap_get_gpio_datain(18)); omap_set_gpio_direction(19, 1); omap_set_gpio_dataout(19, 0); printf("19: = %d\n", omap_get_gpio_datain(19)); omap_set_gpio_direction(20, 1); omap_set_gpio_dataout(20, 1); printf("20: = %d\n", omap_get_gpio_datain(20)); When I turned on the gumstix, GPIO 17 printed out a value of 0 and GPIOs 18-20 printed out a value of 1. However, these appear to be overwritten once the Linux Kernel starts loading. Once the Linux kernel finished booting, I checked the values of all the GPIOs via: "echo 17 > /sys/class/gpio/export" "cat /sys/class/gpio/gpio17/value" (returned 1) No matter what I do, the GPIOs always have a new value of 1 overwriting whatever value I set in u-boot. I can set GPIO 16(the WiFi GPIO) to a value of 0, but I can't set GPIOs 17-20 to 0 even when I run "echo 0 > /sys/class/gpio/gpio17/value". Does anyone know how I can keep the Linux kernel from overwriting the GPIO values I set in u-boot? -- View this message in context: http://old.nabble.com/U-boot-GPIO-values-overwritten-tp32149795p32149795.html Sent from the Gumstix mailing list archive at Nabble.com. |

Howdy, RE preventing the kernel from nuking your u-boot preference settings: I don't believe there is a way. That said, you can inspect what the kernel -is- doing and modify it by looking (assuming you are using linux-omap3) here: $OVEROTOP/tmp/work/overo-angstrom-linux-gnueabi/linux-omap3-2.6.<insert_yo ur_kernel_version_here>/git/arch/arm/mach-omap2/board-overo.c You'll want to look for two things: 1) Is the kernel messing with your mux settings. 2) Is the kernel reserving the gpio for its own ends.

You might actually need to recompile the linux kernel to stop this from happening. There are lots of drivers on the system all doing different things as the kernel boots. Possibly a driver for some device is using the GPIO line. I had the same issue on the Verdex 6LP with what I think might have been video output as Gumstix booted. In the end to prevent the line being used for something else we ended up having to recompile the kernel. -----Original Message----- From: Akram Hameed [mailto:ak...@aq...] Sent: 28 July 2011 00:38 To: General mailing list for gumstix users.

if you mean, can you watch your gumstix boot, via the serial port, on a windows 64 bit machine, yes you can. TeraTerm works on windows 64 Bit, but transferring files on the windows machine to the gumstix board is not recommended.

Hi Jenna; You can, as the other poster said, watch and to some extent control the boot process of a Gumstix from any PC that can run a serial communications program such as SmartTerm. The Gumstix should boot all by itself, "out of the box". In order to write and compile code, you need either a cross-compiler on your PC or a Gumstix image that contains the GCC compiler and other components ...

Christopher, you were right. I ended up having to re-build the kernel. Here is the change I made in /arch/arm/mach-omap2/omap_hwmod.c: if (!(oh->flags & HWMOD_INIT_NO_RESET)) { // I commented out this line //_reset(oh); /* * OCP_SYSCONFIG bits need to be reprogrammed after a softreset. * The _enable() function should be split to * avoid the rewrite of the OCP_SYSCONFIG register. */ if (oh->class->sysc) { _update_sysc_cache(oh); _enable_sysc(oh); } } Now the Linux kernel no longer overwrites the GPIO values I set in the u-boot. However, I need to refine my fix. I don't really understand the change I made. Oh, and I also realized why I couldn't change the values of the GPIOs once the kernel finished booting. echo out > /sys/class/gpio/gpio17/direction Hey, mistakes like that can happen to anyone. You might actually need to recompile the linux kernel to stop this from happening. There are lots of drivers on the system all doing different things as the kernel boots. Possibly a driver for some device is using the GPIO line. I had the same issue on the Verdex 6LP with what I think might have been video output as Gumstix booted.

I don't use Eclipse for development, so I can't be of much help there :( However. Have you tried to connect to the Tobi with a "simple" serial program ?? Something like Smartterm or what ever works with Windows 7 ? I assume you are using Windows 7 or Vista ??

Hi Jenna; You can, as the other poster said, watch and to some extent control the boot process of a Gumstix from any PC that can run a serial communications program such as SmartTerm. The Gumstix should boot all by itself, "out of the box". In order to write and compile code, you need either a cross-compiler on your PC or a Gumstix image that contains the GCC compiler and other components ...
