persistent environment

[Vincent Legoll]

Hello,

I'm struggling to setup u-boot to be able to save the environment.

The board is Pine64 QuartzPro64.

ATF is collabora's:
https://gitlab.collabora.com/hardware-enablement/rockchip-3588/trusted-firmware-a.git
collabora-enablement-tfa/master
44418fce30938ee483fbfc79cc32fde33753d1aa

rkbin is
https://github.com/rockchip-linux/rkbin.git
master
a2a0b89b6c8c612dca5ed9ed8a68db8a07f68bc0

U-boot is:
https://source.denx.de/u-boot/u-boot.git
master
1630ff26cc960439b5949b80cfc604a2c8aa47dd

export BL31=../trusted-firmware-a/build/rk3588/release/bl31/bl31.elf
export ROCKCHIP_TPL=../rkbin/bin/rk35/rk3588_ddr_lp4_2112MHz_lp5_2736MHz_eyescan_v1.11.bin
make quartzpro64-rk3588_defconfig
make CROSS_COMPILE=aarch64-linux-gnu-

SD card is GPT partitionned:
Device           Start     End Sectors  Size Type
/dev/mmcblk1p1      64   16383   16320    8M Linux filesystem
/dev/mmcblk1p2   16384   32767   16384    8M Linux filesystem
/dev/mmcblk1p3   32768   65535   32768   16M Linux filesystem
/dev/mmcblk1p4   65536 1114111 1048576  512M EFI System
/dev/mmcblk1p5 1114112 8388607 7274496  3.5G Linux filesystem

I put on:
* mmcblk1p1: idbloader.img
* mmcblk1p2: u-boot.itb

environment should be on : mmcblk1p3

I tried to use:
CONFIG_ENV_IS_IN_MMC=y
CONFIG_SYS_MMC_ENV_DEV=1
CONFIG_SYS_MMC_ENV_PART=3
CONFIG_ENV_SIZE=0x1f000
CONFIG_ENV_OFFSET=0x3f8000

I tried to add:
* USE_ENV_MMC_PARTITION

I tried to change ENV_OFFSET to 0x0

I'm getting:

Loading Environment from MMC... MMC partition switch failed
*** Warning - MMC partition switch failed, using default environment
[...]
=> env info
env_valid = valid
env_ready = true
env_use_default = true
=> env erase
Erasing Environment on MMC... MMC partition switch failed
MMC partition switch failed
Failed (1)
=> env select MMC
Select Environment on MMC: OK
=> env select MMC 1:3
Select Environment on MMC: OK
=> env erase
Erasing Environment on MMC... MMC partition switch failed
MMC partition switch failed
Failed (1)

I've attached the config and a more complete serial console log.

I'm probably doing something wrong, but I can't see it.

I'd like some hints about how to get further.
Thanks
