The current layout system will only limit the actually written area, not change the requirements of the flash file being the size of the chip, so in this case you'd need to pad the bootloader.img to 8MB.

Writing to a specific Flash region with Layout approach
by Pradeep Ch 01 Aug '16

01 Aug '16

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.

Do you power the whole setup via the OCD? That might be the culprit. I presume that it can not supply enough current in all operating modes. Apparently it is enough to probe for the chip though... -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
