Hi Heinrich and Michael,
Another thing i see is that I missed a patch, for the 3288 gpio0, its iomux is special, there is no high 16-bit write-enabled bit. For Tinker board, it uses I2C0, the current driver will overwrite the I2C0 iomux, while request the GPIO0A4. It requires a patch:

Hi
[U-Boot] [PATCH 3/5] rockchip: rk3288-vyasa: increase heap space after relocation
Can you check it if you have the same problem?
Applying all the changes causes SPL not to start.
CONFIG_SYS_MALLOC_F_LEN=0x4000 does not solve the problem.
Best regards

Hello David, the SPL image size now just fits: Image Type: Rockchip RK32 (SD/MMC) boot image Data Size: 30720 bytes SPL is successful. But MMC is failing in main U-Boot: ``` U-Boot SPL 2019.04-rc1-00239-gb89074f650 (Feb 17 2019 - 12:41:39 +0100) Returning to boot ROM...

With some debug output enabled: ``` U-Boot SPL 2019.04-rc1-00239-gb89074f650-dirty (Feb 17 2019 - 13:05:10 +0100) Returning to boot ROM... mmc_bind: alias ret=0, devnum=1 env_init: Environment MMC init done (ret=-2) U-Boot 2019.04-rc1-00239-gb89074f650-dirty (Feb 17 2019 - 13:05:10 +0100) Model: Tinker-RK3288 DRAM: 2 GiB mmc_bind: alias ret=0, devnum=1 MMC: dwmmc@ff0c0000: 1 Loading Environment from MMC... ``` Any suggestion how to proceed?
