用xfel在ram里面运行程序是没有问题的，也能检测到spinand

所以我使用sudo xfel spinand splwrite 2048 1048576 output/xboot.bin这条命令，烧写以后已经退出了FEL，但是没有启动LOG。
在sys-copyself.c里面的get_boot_device默认是return BOOT_DEVICE_SPINOR;改成return BOOT_DEVICE_SPINAND;
在sys_copyself的一部分改成
else if(d == BOOT_DEVICE_SPINAND)
{
struct zdesc_t * z = (struct zdesc_t *)__heap_start;
void * mem = (void *)__image_start;
void * tmp = (void *)z + sizeof(struct zdesc_t);
uint32_t size = __image_end - __image_start;
#if 0
sys_mmu_init();
sys_spinand_init();
sys_spinand_read(1048576 + 65536, z, sizeof(struct zdesc_t));
sys_spinand_exit();
if((z->magic[0] == 'Z') && (z->magic[1] == 'B') && (z->magic[2] == 'L') && (z->magic[3] == '!'))
{
//if(sys_verify((char *)z->pubkey, (char *)z->sha256, (char *)z->signature))
{
uint32_t csize = (z->csize[0] << 24) | (z->csize[1] << 16) | (z->csize[2] << 8) | (z->csize[3] << 0);
uint32_t dsize = (z->dsize[0] << 24) | (z->dsize[1] << 16) | (z->dsize[2] << 8) | (z->dsize[3] << 0);
sys_spinand_init();
sys_spinand_read(1048576 + 65536 + sizeof(struct zdesc_t), tmp, csize);
sys_spinand_exit();
//if(sys_hash((char *)(&z->majoy), (sizeof(struct zdesc_t) - 100) + csize, (char *)z->sha256))
{
sys_decompress(tmp, csize, mem, dsize);
}
}
}
else
#endif
{
sys_spinand_init();
sys_spinand_read(1048576, mem, size);
sys_spinand_exit();
}
}但是没能启动成功，求大佬支支招。

我在F1C200S上按上面的方法也能启动，但在T113上就没能启动，好奇怪啊。

@xboot
大佬好，我这边是已经修改了get_boot_device()里面的启动介质，改成了BOOT_DEVICE_SPINAND，但还是没能启动
这是编译的结果

}我在开头加上了一个test打印程序，但是没看到有信息打印，uart使用的是0,我看了下寄存器和sys_uart_putc()的地址是一样的
