Seems like it was just a JTAG clock rate issue ... now that I'm trying to use OpenOCD to debug some bootloader code, such issues become more significant. :) I'll be checking in some updates to the User's Guide to highlight where those clocking concerns should show up in the config files; and a few config file updates to match those. Briefly: the scan chain verification after reset must work even if the ROM boot loader can't find a second stage loader to set up (faster) CPU clocking... best way to do this is with a "reset-start" event handler that sets a lower JTAG clock rate. That's not a very widely used handler! - Dave _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
