Part Number: MSP432P401R
Tool/software: TI-RTOS
Fellow MSP users,
The SDSPI example provided with TI-RTOS doesn't work properly. The below error message kept displaying when the SD card was mounted and even when the driver was removed from the launchpad. I am using the latest version of TI-RTOS 2.20 along with the latest compilers (TI 15.12.3 LTS / TI 16.12.0 STS) along with the latest MSP432ware. I am using the CCS version 6.2.0 and have it installed in the default location. I imported the project from Resource Explorer and followed its instructions.
I tried adding a time delay in the middle and tested using an oscilloscope but a clock signal was not present. Therefore I think the problem is in the library and not in the board since I got a clock signal from the designated pins on the board. I checked on the .cfg file and assured that all the configurations were present.
I am not using a SD module shown below. The error would occur even when the SD card module is removed hence I think that the board is not giving an output, but just running the programme.
The code is below.
