funny, the same thing happened to me on my connex400 it said it was protected on a regular filesystem image flash, even after = that range was un-protected. I tried re-flashing the whole thing (u-boot included) and it died. = apparently my flash is fried. -----Original Message----- From: gum...@li...

As unlikely as it seems that I would fry U-boot, because c'mon, you'd have to confirm it.. I did issue the command 'protect all off' before writing to memory. I knew what I was doing was stupid and risky, but when I followed the directions from the Tutorial (which I had followed several times before), The gumstick replied that the memory had been protected (which it was not before).=20 This time, I had installed the CF card on the 80pin highrose. Could that have caused this strange behavior? In any case, due to my stuipidity, looks like I need to figure out how to reflash this thing. Craig, it says on the www.gumstix.com that they(you?) can provide the tool needed to reflash the device. Do you know anything about this?

that was my exact scenario too BTW -----Original Message----- From: gum...@li... [mailto:gum...@li...]On Behalf Of Craig Casey Sent: Friday, June 10, 2005 11:26 AM To: gum...@li...

Each time I did this, upon attempting to boot, the console would print that the kernel (or filesystem?) failed a CRC check. So, at this point, I rebuilt the default image and I prepared to flash it to the device. After building the image, as usual, I issued a "loadb a2000000" to load the image to memory, then transfered it, and then issued a "era 1:2-31".=20 Strangely, the device required confirmation because it said the memory was protected. I did not understand why it required confirmation on not the first 2 sectors, so I tried this more than once, but each time, the same thing happened. Eventually, since my system was inoperable if I did not flash the device somehow (the CRC errors), I said "protect all off" and followed the rest of the directions. Then the device would not boot at all. > you still need to get the executable code to the CPU somehow, which = means > JTAG if your existing bootloader in flash is hosed. =20 If I buy a JTAG, is the software that I need to do this expensive?=20 Sorry to keep bothering you, but I really can hardly afford the JTAG itself and want to make sure that If I go out on a limb and buy it that I dont need to buy some $1,000 software package.

If I want add to Gumstix (Connex type) SD/MMC card slot? then I create custom board, and use 5 (SDATA_OUT), 15 (SDATA_IN1), 43 (SDATA_IN0) and other pins of "Hirose 60 pin connector"? Or SD-slot dont present in connectors and I must emulate him? |

Strange, Did you have a cfstix installed when it happened? Maybe the cfstix causes some funny addressing issues which would explain why my stix died when I didnt flash the first two sectors, and why yours may not have put Uboot on the proper sectors when you flashed it.
