SDcardread issue Tiva123gxl

[shijogeorge24]

hey all ,

I was working with a Tiva C to use an SD card. Even though the log says the bring-up is successful, I can't mount the device. How can I fix this issue? I have tested with 4GB, 8GB, and 16GB cards. None of them seem to be working.

Could you check that the card is formatted Fat32 (xFat or other formats are not supported).

So i changed the maximum SPI clock from 20MHZ to 400KHZ still the same issue exist

The handshake is fine at 400khz, try changing to that.

Shijo, if you can use same sdcard with a STM32 board with SDCard support, this way you confirm your setup is correct

[shijogeorge24]

The only STM32 board I have with me is the STM32L4R5ZI-P. I don't see support for that board on this page: https://nuttx.apache.org/docs/latest/platforms/index.html. Is there any support for this board?

I think for STM32L4 family only the board nucleo-l496zg has support. It is better to use a generic STM32F4 board, like STM32F4Discovery

[shijogeorge24]

i have tested with stm32f411re board

nsh> mount -t vfat /dev/mmcsd0 /mnt spi_setmode: mode=0 spi_setbits: nbits=8 spi_send: Sent: 00ff Return: 00ff Status: 02 nsh: mount: mount failed: 19

attaching my config file is there something missing in the config file ?

https://github.com/shijogeorge24/stm32f411re/tree/main/nuttxspace/nuttx

here is the code i am using

[acassis]

@shijogeorge24 did you try to format the card as FAT32 using NuttX mkfatfs?

https://acassis.wordpress.com/2023/11/25/how-to-format-sdcard-on-nuttx-terminal/

[shijogeorge24]

The issue has been resolved. The problem was that the CS line was not configured at all https://github.com/apache/nuttx/blob/38664cee7853a7fa4334d64a063de5e68ecb0ecc/arch/arm/src/tiva/common/tiva_ssi.c#L1513 . I assumed that whenever we call the function tiva_ssibus_initialize(), it would take care of initializing all the necessary pins, but that was not the case for the CS pin, which was left for the user to configure. At the moment, I have hardcoded the CS pin in the tiva_ssibus_initialize function. Is there a better way to handle this?

[acassis]

Hi @shijogeorge24 the chip select should be configured at tm4c_ssidev_initialize() as it is done for MCP2515.

If you finally got everything working, please close this issue.
