Hi,
I have an Intel 28F640J5 part in x16 mode. It appears I can't read
bytes which are odd aligned. After reading one odd aligned byte all
reads fail.
I'm using the 1_by_16 routines in cfi_cmdset_0001.c

Reading the specs for this chip indicates that the high byte is not used
for command or status information. So I changed
do_read_1_by_16_onechip() to align commands and status reads on word
boundaries.
