Part Number: MSP432P4011
Other Parts Discussed in Thread: SYSCONFIG
Tool/software: Code Composer Studio
Hi,
I've been trying to integrate SD memory into a system using MSP432. I have been trying to use the examples directly in the SDK (sysconfig -> RTOS -> freeRTOS).
I've tried fatsd, fatsdraw, and sdraw, Every example seems to get stuck on the f functions. E.g. f_getfree, f_open, fopen.
The UART output is identical, whether or not a card is inserted.
Starting the FatSD Raw example
This example requires a FAT filesystem on the SD card.
You will get errors if your SD card is not formatted with a filesystem.
Drive 0 is mounted
Reading disk information...
When I probed the SPI signals I noticed that there is no SPI activity what so ever. The chip select remains high, and there is no activity on SCLK, MISO, or MOSI pins
I've triple checked this against my layout, and my pin numbers match the definitions in sysconfig. However, it looks like the MCU has no traffic on this SPI lane at all.
Is there something additional that I'm missing that is not in the SDK? I've been using fatsd_MSP_EXP432P4111_freertos_ccs_syscfg as a base board, changing only which pins the SPI and CS are using in the sysconfig. The display still has output, so I know RTOS and the thread is working.
Thanks,
Eric
