QSPI NOR flash boot programming

Thank you Georgi for your comment, Hello Allen, This approach will be always slow. But once you flash-ed the image then the update could be done quite fast depending from few things. networking support in that linux image mtd utils present in linux image Once programmed the image, you will be able to transfer the next image file into DDRAM (ramfs) with ftp or sftp and then usind mtd utils (flashcp, flash_erase, etc...) to program the image to the device. it will be significantly faster.
