AT91RM9200 USART machine reset problem

Thu Apr 26, 2007 5:58 pm

Hi, all,

I've got linux 2.6.20.2 patched from maxim.

When I access /dev/ttyAT2 (AT0 = DBGU, AT1-4 are USART0-3) I get a reset from the device. I don't get a kernel panic or any such debug, I just get a reset.

Using the port outside of linux (from test code written to run straight out of SDRAM w/ no OS) works great on all 5 ports.

Has anyone seen anything like this?

Thanks,

Matt Gessner
