How to tranfer binary from payolads to code

[bdn76]

Hi!

I'm need to make some change in payloads for r528_t113 SPI. I'm make binary but how to remake corresponding C file in chips dir (r528_t113.c)? I'm talk about this section:

static int chip_spi_init(struct xfel_ctx_t * ctx, uint32_t * swapbuf, uint32_t * swaplen, uint32_t * cmdlen)
{
        static const uint8_t payload[] = {
                0x00, 0x00, 0xa0, 0xe3, 0x17, 0x0f, 0x08, 0xee, 0x15, 0x0f, 0x07, 0xee,
                0xd5, 0x0f, 0x07, 0xee, 0x9a, 0x0f, 0x07, 0xee, 0x95, 0x0f, 0x07, 0xee,
                0xff, 0xff, 0xff, 0xea, 0x5c, 0x00, 0x9f, 0xe5, 0x00, 0xd0, 0x80, 0xe5,
...

Tnx
