Hi, I applied the patches that were recently posted for the SST flashes (my board has SST39VF1601) and I can say they work! A big thank you!
I'm running SVN 1470M. I've been able to use my JTAGkey to read/write flash but I flashed a bum u-boot.bin and now I hosed the board and OpenOCD reports I've lost JTAG communication. The board can be boot strapped to boot from dataflash or NAND flash instead of the NOR flash I've been working with. When I boot via another flash that still has a good u-boot that properly boot straps the board, OpenOCD and my JTAG interface works. This leads me to believe that I don't have enough in my init-reset routine to properly boot strap the board. I thought I could just use the u-boot source to figure out the right settings to the registers to set up the clock/PLL, SDRAM etc., but the code that does this isn't in one section, it is spread out over usb modules, serial modules and even lcd modules. Anyone got experience with bringing up the AT91SAM9260 based boards and know what the min init is? Can I use the working u-boot to probe these registers and figure out the settings that way? The board came with EasyICE (which is a parallel wiggler) and a software tool to reflash the NOR flash, but I've tried it on two different computers and can't get it to work. I wish I had the source to this utility because I'm sure it holds the key to the proper init sequence of the board. Thanks! Brian
