I've made my first AT91SAM9260 board. It is based on Atmel's '9260-EK, but has no NAND flash (at least).
In file "CustomApplet.txt" (from SAM-BA) I read that I have to change some scripts to make it work with my custom board.
Before I do that, is SAM-BA able to connect with my board, at all? I power-on my board then start SAM-BA and select original "at91sam9260-ek" and nothing happens - i.e. the prog freezes.
When I first started this, I've mistakenly connected RX & TX the wrong way to the MAX3232 and SAM-BA said "No valid processor ID found". I've connected RX & TX correctly now and SAM-BA just sits, forever.
However, before that, I should be sure that my oscillators are working. Well, they both work (32kHz and 20MHz) but the voltage swing is very low - between 0 and 0.5 V, is that OK? The frequency itself is OK.
