Moving from STM32L476xx to STM32L4R9xx

[machinehum]

After spending some time looking into the R9 I decided to make the switch. I've been developing on the 76 for a while now. I read the migration document and it doesn't look like there are any differences.

​

Right now I'm having issues with spi and sd card / fatfs stuff. After several days of reading I really can't figure out what's goin on. I've changed the linker script, startup.s asm, and the define in the Makefile. I know the sdio driver uses an internal DMA, so I just pulled out the DMA stuff and linked up a callback... No dice. For the spi I changed the clock divider because I'm running the hclk faster (120)

​

I'll post some code tommorow but I have to be missing some major component...​

Looks like you've got DMA on SDMMC handled differently on L4+

CLOCKDIV math also different, and peripheral clock sourcing. So CLKCR and HSI/PLL sources

Perhaps check command line option/defines, and merge in example code from an L4+ BSP

 RCC_OscInitTypeDef    RCC_OscInitStruct;

 RCC_PeriphCLKInitTypeDef RCC_PeriphClkInit;

 /* Check whether HSI48 is enabled or not */

 HAL_RCC_GetOscConfig(&RCC_OscInitStruct);

 if(RCC_OscInitStruct.HSI48State != RCC_HSI48_ON)

 {

  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI48;

  RCC_OscInitStruct.HSI48State   = RCC_HSI48_ON;

  RCC_OscInitStruct.PLL.PLLState  = RCC_PLL_NONE;

  if(HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)

  {

   while(1) {}

  }

 }

 /* Configure the SDMMC1 clock source. The clock is derived from the HSI48 */

 RCC_PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_SDMMC1;

 RCC_PeriphClkInit.Sdmmc1ClockSelection = RCC_SDMMC1CLKSOURCE_HSI48;

 if(HAL_RCCEx_PeriphCLKConfig(&RCC_PeriphClkInit) != HAL_OK)

 {

  while(1) {}

 }

I'm not using the HSI48, I routing through some PLLs to generate my clock for SDMMC1. Here is my clock code.

Alright I've gotten the spi working again by calling

__HAL_RCC_DMAMUX1_CLK_ENABLE();

Hopefully it's something similar to this with the sd card stuff
