I have tried u-boot for the imx27lite board from LogicPD which is currently in u-boot-arm repository and I have experienced some stability problems:
- Sometimes the system gets stuck in serial_getc() from serial_mxc.c
driver when printing information (ex. mii read ).
- Pings do not work properly, the system gets stuck in fec_send()
function waiting always for a frame to be sent (which actually does not happen).
- Sometimes the system gets stuck when saving the environment to flash
'saveenv', but other times it does it well.
We don't see any such issues on the board we have here in the lab.
I would like to help to solve this problems, but I don't know exactly where to begin from. I have been reviewing clock settings. Could this be happening because this board is using 32KHz xtal as reference instead of 26MHz one?
Yes, of course this could be a problem. Is this an original LogicPD board? Did you adapt the code for the different clock speed? What exactly did you change?
Have you experienced these problems also?
No, we didn't.
Best regards,
Wolfgang Denk
