IMX8Mp on android11 change emmc from 16G to 64G

[c-luo]

Hi NXP: I encountered some problems while debugging the EMMC size, I hope to get your support. Because some reasons,we changed EMMC from 16g to 64g. So,i need to change code.

first: change my BoardConfig.mk add 56G-ab_super.bpt # Support gpt ifeq ($(TARGET_USE_DYNAMIC_PARTITIONS),true) BOARD_BPT_INPUT_FILES += $(CONFIG_REPO_PATH)/common/partition/device-partitions-13GB-ab_super.bpt ADDITION_BPT_PARTITION = partition-table-28GB:$(CONFIG_REPO_PATH)/common/partition/device-partitions-28GB-ab_super.bpt \ partition-table-54GB:$(CONFIG_REPO_PATH)/common/partition/device-partitions-54GB-ab_super.bpt \ partition-table-dual:$(CONFIG_REPO_PATH)/common/partition/device-partitions-13GB-ab-dual-bootloader_super.bpt \ partition-table-28GB-dual:$(CONFIG_REPO_PATH)/common/partition/device-partitions-28GB-ab-dual-bootloader_super.bpt

change device-partitions-54GB-ab_super.bpt

"settings": {
"disk_size": "54 GiB",
"disk_alignment": 2097152,
"partitions_offset_begin": 8388608
},

$ sudo ./uuu_imx_android_flash.sh -f imx8mp -e -c 54

My board can't get into Android interface when it starts for the first time after downloading the code，need input reboot command,then it can Normal use.

The first startup log Please check the attachment log-err.txt.

I tried to change the EMMC size to 13G，It won't have this problem.

Looking forward to your reply, thank you!
