Uboot not seeing the sd card that it was loaded from

[dkal]

When I start uboot it says MMC: STM32 MMC: SD/MMC:0 and STM32 SD MMC: 1 but then it won't boot linux saying "No block device".  I have looked at the eval board DTS and tried to include as much relevant items as I could but am not getting any signs of life. The mmcinfo and mmc commands show nothing except the list command which just shows the same STM32 MMC: SD/MMC:0 and STM32 SD MMC: 1.    I have added cd-gpios to the sdmmc1 with the gpio active low and confirmed with the gpio command that the cd pin is low when a card is present.  Hoping someone can point me in the right direction.

Turning on some debug info:

stm32_mmc2 mmc@58005000: stm32_sdmmc2_getcd called

stm32_mmc2 mmc@58005000: bus_with = 0, clock = 0

stm32_mmc2 mmc@58005000: bus_with = 1, clock = 0

stm32_mmc2 mmc@58005000: bus_with = 1, clock = 400000

stm32_mmc2 mmc@58005000: send cmd 0 data: 0x0 @ 0x0

stm32_mmc2 mmc@58005000: timeout reading SDMMC_STA register

stm32_mmc2 mmc@58005000: send STOP command to abort dpsm treatments

stm32_mmc2 mmc@58005000: end for CMD 0, ret = -110

Also should note I couldn't get the MCU clock to be driven by PLL3P, It hangs in optee, so it is driven by HSI right now.  Since that clock drives the PCLKs I can see this could be the issue, but in that case I need to know why I couldn't select PPL3 as the MCU clock.

I got the card to recognize by switching the mmc1 clk mux to hclk6.  So there is still the issue of why my pll3 and pll4 settings don't seem to work

Turns out I didn't configure the PLLs in TF-a so it didn't like it when they were configured in optee.
