How to find an exact address in memory to upload the file to?
Memory SPANSION S25FL064P datasheet.
I want replace binary data ("nvram") in Flash memory with new data. For this, I have to download binary data to flash memory, then erase memory in specific location, then copy the above downoaded file into specified memory address. All this operations from U-Boot. The U-Boot commands:
loadb [ offset ] --> what is this address?
erase [start] [end] - erase FLASH from addr 'start' to addr 'end
cp.b [source] [target] [count(number of bytes)]
What should be adresses in this commands?
