we are developing custom board based on i.MX7D-SABRE but we use different qspi nor flash: is25wp256d , is25wp512m by ISSI. We miss for them the requested header configuration file to write on the flash using mfgtool to allow i.mx7 to boot from them: what is the way to get these files or the easier method to write it by myshelf ? Inside the mfgtool there are only header config files for some flash by macronix/micron/spansion (qspi-nor-macronix-mx25l51245g-config,qspi-nor-micron-n25q256a-config,qspi-nor-spansion-s25fl128s-config ).
We have already a custom u-boot and linux kernel booting from sd card and running on our board and the qspi nor flash (is25wp256d) is recognized both from u-boot and kernel.
Thanks much in advance,
