Hi,
I am trying to run DFU in order to flash u-boot.imx into the SD card on a mx6qsabresd.
The changes in config file are:
--- a/include/configs/mx6sabre_common.h +++ b/include/configs/mx6sabre_common.h @@ -295,4 +295,10 @@ #define CONFIG_G_DNL_PRODUCT_NUM 0xa4a5 #define CONFIG_G_DNL_MANUFACTURER "FSL"
+#define CONFIG_CMD_DFU +#define CONFIG_DFU_FUNCTION +#define CONFIG_DFU_MMC +#define CONFIG_SYS_DFU_DATA_BUF_SIZE SZ_32M +#define DFU_DEFAULT_POLL_TIMEOUT 300 + #endif
=> mmc dev 1
=> setenv dfu_alt_info 'boot raw 0x2 0x400' => save
=> dfu 0 mmc 1
Then on the host PC:
$ sudo dfu-util -D u-boot.imx -a boot dfu-util 0.8

and the following error is seen in U-boot:
dfu_get_buf: Could not memalign 0x2000000 bytes
Does anyone have any suggestions about this?
Thanks,
