How to write data to the SPI flash on startKIT? Topic is solved

[mogren3000]

Hey. I have been testing the ALU the startKIT and i want to mesaure something else, so i thought that write and dump into memory. and then take some time on this.
But there is no documentation on how to use the SPI Flash on the startKIT, only for the slicekit.
So how is this done?

Try libflash:https://github.com/xcore/sw_flashlib_examplesIt essentially doesn't matter on which platform you deploy it, startKIT or SliceKIT or something else.At most you need to configure which ports to use (if the flash chip isn't hooked up at the default pins)

Why does it not work.

The console is writing me this;

FLASH fitted : WINBOND W25X20.
FLASH size: 262144 bytes.
FLASH page size: 256 bytes.
FLASH data partition size: 0 bytes.
FLASH number of pages in data partition: 0
FLASH number of sectors in data partition: 0
FLASH data sector size: 0 bytes.
Data partition erased!
Could not write the data partition

Why cant it write and read from it as it supposed to do.. I have tried all the diffrent macros from SpecMacro.h and have ben setting the XCC_FLAGS in make file. to -lflash

The only thing that needs to be modified is changing the target to STARTKIT in app_flashlib_example/Makefile

Code: Select all
