Can you edit arch/arm/cpu/arm926ejs/cache.c and change the debug() to printf() , then re-test please ? I suspect this might trap something still. Ah, and please test on u-boot-usb/master with this patch.
No additional output on the console.
What does this mean? Do you see warning messages prefixed with "CACHE: " ?
No messages prefixed with "CACHE: ". Just the usual error message.
I am sorry, but maybe I edited arch/arm/cpu/arm926ejs/ in a another branch and compiled in u-boot-usb. If I run now tftp with printf enabled in arch/arm/cpu/arm926ejs/cache.c I get the following "CACHE: " messages:
CACHE: Misaligned operation at range [40008000, 4000c653] CACHE: Misaligned operation at range [43fd0b0c, 43fd0b60]That happens right when you first use the UDC driver right? If so, I hope that "[U-Boot] [PATCH 1/6] usb: ci_udc: fix ci_flush_{qh, qtd} calls in ci_udc_probe()" will fix that.
Checkout clean u-boot-usb/master, applied board specific patches and applied the mentioned patch. Running tftp three times in a row:
