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

Yes, please update line 33 in your config file, at least with this
#define CONFIG_SYS_MALLOC_LEN (10 * SZ_1M) + CONFIG_SYS_DFU_DATA_BUF_SIZE
You don't have enough malloc memory reserved.
Best regards,

This fixes the problem :-)
Thanks a lot for your help!

No problem. You uncover one more thing, which should be done before change the dfu mmc static buffer with memalign, which is increase the malloc memory, for configs with dfu.
