Yes. For CFI compliant chips features like sector count, sector sizes etc are autodetected. No need to define the chip with it's ID anywhere. > How I can crosscheck that present Uboot V2009.08 works for M29W128GH?

You should test it with the latest version of mainline U-Boot: http://git.denx.de/?p=u-boot.git;a=summary Please note that you need to add a board specific flash_cmd_reset() function for this chip to work correctly. Something like this should work (untested): void flash_cmd_reset(flash_info_t *info) { flash_write_cmd(info, 0, 0, AMD_CMD_RESET); } Cheers, Stefan -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-0 Fax: (+49)-8142-66989-80 Email: off...@denx.de _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
