I also stumbled with the same problem of board resetting but it was in order of MBs and not in KBs. Board gets reset while performing burst erase/write(for 48M erase, resets at 16M~) and read operation on 16M+. I provided fix [1] in driver itself(add 1us delay) assuming it to be soc specific which solves problem for me and able to perform complete flash size operations.
