Holger, Robert, Kevin thanks very much - each of your replies have been very enlightening!
I've been poking around with reading / writing individual registers using HaRET too, so I think I'll try to just get a GPIO logic signal out first on the STUART, like you said Holger, and then check that the uart clock is running (i'm fairly certain that it was). In regards to the linux kernel output on the FFUART - that would explain A LOT !! I couldn't understand why I wasn't seeing a single character, let alone a flicker on the scope, but now that makes complete sense. Thanks for clearing that up for me Robert ! Each of the uarts has fairly similar configuration registers, so I should be able to change Linux to write to the STUART instead. This has been tremendously helpful - maybe if I buckle down this weekend I can get it done before monday ;-) Just to give you an idea, the target that I'm porting Linux to is sooort of like the TDS Nomad - it's a rugged, industrial, handheld mobile computer, and I've been getting a lot of support from both the manufacturers and my company. Both parties are very pro-open-development. The only thing holding them back until this point has been, well.. me! I need to get a successful port working before I can publish any 'official' information, including specific names. Having a few more eyes on the problem really helps a lot - I unfortunately work from home, and have basically been alone on this project since its inception about a year ago (of course, I've been on other projects since then too). Cheers, and thanks again. Chris _______________________________________________ Haret mailing list [email protected] https://handhelds.org/mailman/listinfo/haret
