I am attempting to write to a flashrom using layout/region approach. The NOR flash size is 8MBytes. The file size I am writing is 106976 Bytes. The rom.layout file contents are: 00000000:0001a1df test1 0001a1e0:007fffff test2 The command I am using is: ./flashrom -p ft2232_spi:type=arm-usb-ocd --layout rom.layout --image test1 -w bootloader.img The error I am getting is : Using region: "test1". Calibrating delay loop... OK. Found Eon flash chip "EN25Q64" (8192 kB, SPI) on ft2232_spi. Error: Image size (106976 B) doesn't match the flash chip's size (8388608 B)! Please let me know about the error. Thanks, Pradeep Ch.
