Hello,
I am working on a custom board, that is based on the NXP T2080 processor.
We have been experiencing issues with our loading process which utilizes tftp to retrieve images for loading into NAND.
The vast majority of the attempts result in "Loading: *" or "Loading: #" with no further output, and u-boot does not respond to ctrl-c and appears to have hung someplace.
Using Wireshark I can confirm the following packet transfers are taking place:
ARP request for our external machine
ARP reply from external machine to u-boot with correct MAC address
TFTP read request from u-boot to external machine
TFTP Option ACK from external machine to u-boot
TFTP ACK block 0 (OACK) from u-boot to external
TFTP data packet 1 from external machine to u-boot
(and then the further retries of packet 1)
Thanks,
Matt
