I am trying to bring up SDMMC1 on an STM32H743 using ChibiOS 21.11.4 and I am completely stuck.
The same board and the same SD card work perfectly with STM32Cube HAL.
With ChibiOS, the SDMMC peripheral appears to be electrically dead.
- Symptoms:
* SDMMC1 registers are accessible and writable
* AHB3 clock is enabled (`RCC->AHB3ENR` SDMMC1EN bit is set)
* SDMMC kernel clock source is configured (tested both PLL1Q and PLL2R)
* PLLs are running and stable
* `SDMMC->POWER = 0x3`
* `SDMMC->CLKCR` is programmed (e.g. `0x164`, CLKEN = 1)
But:
* `SDMMC->STA` always remains `0x00000000`
* No flags ever appear: no `CMDSENT`, no `CMDREND`, no `CTIMEOUT`, no errors
* Sending CMD0 or any command manually does nothing
* `sdcConnect()` always fails
* Even with no card inserted, there is absolutely no activity
The SDMMC behaves as if the whole peripheral block is not clocked or not powered.
- What I verified in GDB:
* `RCC->AHB3ENR` SDMMC1 bit is set
* `RCC->D1CCIPR` is correctly configured for SDMMC kernel clock
* `RCC->PLL1CR` / `RCC->PLL2CR` show PLLs enabled and stable
* The SDMMC registers can be written and read back correctly
* `SDMMC->CLKCR` has CLKEN = 1
* `SDMMC->POWER = 3`
Yet:
* `SDMMC->STA` stays at 0 forever
- What I tried
* Forcing SDMMC clocks manually in code and in GDB
* Forcing SDMMC kernel clock source (PLL1Q, PLL2R)
* Forcing SDMMC registers manually
* Using both ChibiOS SDC driver and raw register access
* Testing on several different boards (same result)
* Comparing with STM32Cube HAL project (works perfectly there)
- Question:
On STM32H743:
Is there any additional power-domain / PWR / VDDMMC / CR3 / SMPS / LDO / domain enable needed to actually power the SDMMC1 block?
Is there anything specific that ChibiOS does (or does not do) regarding SDMMC power or clock domain enable on H7?
Is there any known missing step or bug in ChibiOS 21.11.x for SDMMC on H7?
And more generally:
Is there something obvious that I might be missing in the STM32H7 SDMMC bring-up sequence?
At this point the peripheral behaves exactly as if the SDMMC block is electrically OFF.
