The source buffer for spi_flash_write should be 4-byte aligned, and it looks like plug_param is not.

I found the problem, I don't understand it but now it works,
I put the code in a function, and called it.
It seems that when the code is in user_init() it does not work.
Once i put it in a function, and called it (from the same place as it was before in user_init) the code works.
I didn't change the code.

As I said it's caused by your struct not being properly aligned. If the source address of spi_flash_write is not a 4 byte multiple an exception is raised. This will force proper alignment:
Code: Select all
struct __declspec(align(4)) plug_saved_param {

I used the same code as before, I don't understand why was it not aligned ?
the same structure. same size.
do you mean that the struct in the memory did not start in an aligned 4 bit address ?
