[U-Boot] dfu_get_buf: Could not memalign 0x2000000 bytes

[Fabio Estevam]

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:

Does anyone have any suggestions about this?

Thanks,
