Hi, We have two patch files for u-boot:
Bootelf_async_abort_fix.patch: Booting a .elf files sometimes triggers an asynchronous abort error disabling the icache and dcahe before boot turned out to prevent this and this patch adds disabling of these caches as a part of the bootelf command.
Tftp_next_ack_update: When running tftp without any additional options (i.e no oack gets sent) the client does not change the expected block number of the next package from 0 to tftp_windowsize preventing acknowledgement of received data. There also was no prober mreset for this counter that instead only reset upon receiveing an oack. This patch increments the value of next_ack when receiving a data packet instead of an oack and also ensures that sending a new read request or write request resets the counter to 0, indicating that the next packet should be an oack.
