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:
http://patchwork.ozlabs.org/patch/1040541/ http://patchwork.ozlabs.org/patch/1040541/
I've also just stumbled onto the issue of recent uboots not booting on rk3288. While your patch seems to have reached patchwork, somehow the u-boot list seems to have lost it - as it's neither in public archives nor in my inbox it seems.
Please note that I had requested changes to that patch during review. I’ll ping David again on when he expect to have those changes implemented and ready.
Applying the patch does not make my board (phycore-rk3288 in this case) get farther though - I'll investigate more.
But it looks like we should be having the same issue in the kernel, just never triggered it, as the gpio0 are of more esotheric uses normally.
Anyway, I'm wondering if defining IOMUX_WRITABLE_32BIT alone wouldn't be enough and use that for iomux, pull and drv, similar to what we do for the pull/drv register source already.
That way we could refrain from introducing DRV_TYPE_WRITABLE_32BIT and PULL_TYPE_WRITABLE_32BIT .

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

<snip>Hello David, hello Philipp,
what are your ideas to reduce the SPL size to under 0x7800 again? Or will you move all rk3288 boards to TPL like TARGET_VYASA_RK3288?
CONFIG_SPL_I2C_SUPPORT is necessary for Tink spl? Remove this can make spl boot. As the Tinker does not use the i2c to read the MAC address from eeprom at the SPL stage, which is at uboot.
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...
