在将 SDK 升级到09.02.01.09的过程中、发现 eMMC 无法在 RAW 模式下启动。 MMC_LOAD_IMAGE_RAW_SECTOR：MMC 块读取错误。
U-Boot SPL 2023.04-gd198909e26-dirty (May 22 2024 - 16:16:28 +0800) SYSFW ABI: 3.1 (firmware rev 0x0009 '9.2.7--v09.02.07 (Kool Koala)') SPL initial stack usage: 13408 bytes Trying to boot from MMC1 ------BOOT_DEVICE_EMMC ------boot_mode: 1 ------spl_mmc_load 4 ------spl_mmc_load 5 ------spl_mmc_load 7 hdr read sector 400, count=1 ------mmc_load_image_raw_sector 1, image_get_magic: 0x0 ------mmc_load_image_raw_sector 1-3 mmc_load_image_raw_sector: mmc block read error ------spl_mmc_load 8 spl_load_image_fat: error reading image tispl.bin, err - -2 SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ###
通过比较08.06.00.42、image_get_magic (header)== FDT_magic、可通过 spl_load_simple_fit ()接口获取图像。 但在09.02.01.09 magic 等于0、image_get_magic (报头)！ = FDT_MAGIC。
static __maybe_unused
int mmc_load_image_raw_sector(struct spl_image_info *spl_image,

int ret = 0;
header = spl_get_load_buffer(-sizeof(*header), bd->blksz);
/* read image header to find the image size & load address */

image_get_magic(header) == FDT_MAGIC) {

struct spl_load_info load;
debug("Found FIT\n");
load.dev = mmc;
load.priv = NULL;
load.filename = NULL;
load.bl_len = mmc->read_bl_len;
load.read = h_spl_load_read;
ret = spl_load_simple_fit(spl_image, &load, sector, header);
} else if (IS_ENABLED(CONFIG_SPL_LOAD_IMX_CONTAINER)) {
printk("------mmc_load_image_raw_sector 1-2\n");
struct spl_load_info load;
load.dev = mmc;
load.priv = NULL;
load.filename = NULL;
load.bl_len = mmc->read_bl_len;
load.read = h_spl_load_read;
ret = spl_load_imx_container(spl_image, &load, sector);
} else {
printk("------mmc_load_image_raw_sector 1-3\n");
ret = mmc_load_legacy(spl_image, mmc, sector, header);
}
end:
if (ret) {
#ifdef CONFIG_SPL_LIBCOMMON_SUPPORT
puts("mmc_load_image_raw_sector: mmc block read error\n");
#endif
return -1;
}
return 0;
}
如果要在 SDK 中支持09.02.01.09 eMMC 原始启动模式、如何调整它？
