Make sure early debugging is enabled in linux and that it is setup to use the correct port. > The 'debug port' on my handheld is actually connected to the STUART > (it's a marvell pxa270 chip), and after checking out the code in > uart.cpp, I noticed that HaRET actually uses the FFUART. I think you got bitten by dead code - the code in uart.cpp is unused as far as I know. Haret doesn't support writing to serial at this point - it would be a nice feature to add. > ...

I recommend trying to get some serial output from Linux as the first step. Once you get feedback from Linux, the remaining work becomes much easier. -Kevin _______________________________________________ Haret mailing list [email protected] https://handhelds.org/mailman/listinfo/haret
