Hi, I have been experimenting with the Freescale M5235EVB for the past couple of months since we are thinking about using this platform with uClinux on it. I think there is a bug with the serial (QSPI) port in the linux 2.6 kernel and I cannot find the problem. I just recompiled the new 20070130, just as I did 20060803, but the 2.6 kernel still boots displaying garbage characters on the serial ports. I've noticed couple of things:
- Kernel 2.6: I can still telnet to the board after boot, log in and everything seems to work just fine and the OS is stable. - Kernel 2.4: Both 20070130 release and 2006803 work ok - 20070130 sometimes resets unexpectedly. No problems with the serial port though. - Kernel 2.6: I tried every possible baud rate setting on the Hyper Terminal to no avail. - I tried checking and comparing the source in kernel/drivers/serial and in arch/m68knommu, but it is like looking for a needle in a haystack when you don't know where to look. - Kernel 2.6: Some of the characters typed from the (Hyper-terminal) keyboard do appear to be correct. I haven't found out why - doesn't seem to be related to their bit-wise representation. No valid characters are received back from the Coldfire. Anybody has any ideas where should I look? Best Regards, Ivica Eftimovski
