Programming FPGA from HPS using QSPI

I found the error.

The error is in the preloader when try to transfer the fpga file.

Looking into the preloader in the file spl.c there is this function:

void spl_program_fpga_qspi(void)

{

struct spi_flash *flash;

struct image_header header;

u32 flash_addr, status, transfer_size;

u32 temp[64];

.....

.....

while (spl_image.size) {

/*

* Read the data by small chunk by chunk. At this stage,

* use the temp as temporary buffer.

*/

if (spl_image.size > sizeof(temp))

transfer_size = sizeof(temp);

else

transfer_size = spl_image.size;

spi_flash_read(flash, flash_addr, transfer_size, temp);

/* update the counter */

spl_image.size -= transfer_size;

flash_addr += transfer_size;

/* transfer data to FPGA Manager */

fpgamgr_program_write((const long unsigned int *)temp,

transfer_size);# ifdef CONFIG_HW_WATCHDOG

WATCHDOG_RESET();# endif

}#endif

when I read the value of the spl_image.size it was half of the full dimension of my rbf program.

I tryed to modify this value by manually writing spl_image.size to the correct value and finally the fpga works.

Now I think that the problem is the header of the .rbf file.

How can I modify the header file?
