I am using intel PXA flash chip to store embedded bootloader and embedded App. It is taking long time (4 minutes) to write 3 MB data. I am writing128k block at a time. It is taking 10 seconds to read.
Any suggestions on improving the speed to write is appreciated. I am new to flash programming. Or is it expected time? Did we select wrong chip for writing such large data. I am designing to avoid reading and writing more times from flash, still for updates entire image needs programming.
Thanks for comments from experts.
