Could you see if this patch[1] fixes the write issue? > Also, it seemed to increase code size on samus by >2KB. > Above commit ports Linux SPI NOR framework in order to support 4 byte addressing SPI NOR opcodes and spi_mem_ops (to support both SPI NOR and SPI NAND flashes using single SPI driver) therefore there is code size increase. But, I did provide SPL_SPI_FLASH_TINY which can be enabled to reduce binary size on resource constraint board. Note that SPL_SPI_FLASH_TINY only supports reading from flash and does not support write (Since SPL just needs to support reading next stage image) [1] http://patchwork.ozlabs.org/patch/1090121/ -- Regards Vignesh _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
