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:
=> reset
