LS1012ARDB SD WiFi "Card did not respond to voltage select!" at uboot

Hi all,

Running a LS1012ARDB here and wanting using the in package provided SD WiFi module.

It's a Murata WiFi one, parted TDA6350.

Just inserting the  module and fire-up u-boot works but later on when booting e.g. Ubuntu kernel it throws a -110 error. Coming back to u-boot again then stay there and try to see SDHC1 device it get this

=> printenv hwconfig
hwconfig=esdhc1
=> mmc list
FSL_SDHC: 0
FSL_SDHC: 1 (eMMC)
=> mmc dev 1
switch to partitions #0, OK
mmc1(part 0) is current device
=> mmc dev 0
Card did not respond to voltage select!
=>

I understand it's linked to voltage select on GPIO23 defined in RCW register.

NOTE: for eMMC device there is another post I submitted here and that works flawlessly.

My question: what is simplest method to correctly set SDHC1_VSEL? Since I suspect it's that one posing trouble here. There is no switch on the board to manage this and it has to go over RCW. If I can simply peek/poke into that one from u-boot in a persistent way then I'd be glad.

Ubuntu kernel throws me this out:

I run a u-boot v2019.04. You can find dts details here

https://elixir.bootlin.com/u-boot/v2019.04/source/arch/arm/dts/fsl-ls1012a.dtsi#L56

Ok still try to figure out how to make work the WiFi module shipped with the LS1012ARDB. User guides and documents are not of a great help. It says: plug-in, works .... nope.

Anybody? Thx Christophe

Let me share the register view of both SDHC interfaces at u-boot stage.

Please, if anybody can help be here I'd be glad - think it's a stupid problem but for now I don't see it.

Thx Christophe
