Hello, all I am developing the system using the NOR flash (32MB) and the core is about 300MHz mips. I wonder how long takes the whole erase and write time to flash memory. I tried it on the bootloader. Firstof all, bootloader(YAMON) load the image and erase the flash except bootloader region, write the image.. It took about 14-16minutes.I think it is too long.
Can't really say, but it seems ok to me. Each chip will have unique timing characteristics which are covered in the data sheet for the flash part with min, typical and max values. You can compute the upper and lower bounds of the operation using that information.
I would like to know, for you, normally how long it tasks ? Thanks,
