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:
...

Loading: ## 4.3 MiB/s done Bytes transferred = 18003 (4653 hex) CACHE: Misaligned operation at range [40008000, 4000c653]
OK, that particular error happens well after the network transfer phase of the tftp command, so is likely nothing to do with ci_udc. It'd be great if you could track it down and fix it though.
Ah, I bet that 40008000 is your load address; the address that the downloaded data is being copied to?
