[U-Boot-Users] Reset problem
Hi folks,
We have a 5282 in our prototype board based in an Avnet board, with the lastest u-Clinux dist. and U-Boot, and we have an annoying behaviour. The 80% times we push the reset button, uClinux don't boot, and we have to plug off the power and plug on to boot correctly. We have checked the reset out signal from the micro, and it's ok.
Best regards,

Hi,
Are you using a flash to boot from? I had a similar problem with an ADI Coyote based board. Turns out that if the flash chip is in "Write enable" mode when the reboot occurs, the CPU can't read the bootloader from it and the board hangs. I added a reset handler in the MTD mapping driver (ixp4xx.ko in my case), which forced the flash chip in to read mode before the reset is attempted.
Regards, Dan...

Hi Dan,
Thanks, the solution was connect the reset line to the reset input from our flash chip. Now it seems all works ok!
