New ContributorHow to read from a Flash and write back to it with Nios Command Shell?
According to the ug_nios2_flash_programmer.pdf,
I have read the data（current.srec） from flash.
And then I want to write the current.srec back to flash.
while the ug_nios2_flash_programmer.pdf says, when program a flash, I need a .flash file.
Is it necessary to convert the .srec file to .flash file?
if it is necessary, could you give me a sample(command)?
Or any other way to read from a Flash and write back to it?
