TM4C129ENCPDT: drivers for TM4C129ENCPDT and TM4C123GH6PM in Code Composer Studio(Linux)

Hi Charles,

Thank you so much for your detailed answer. I'll inform our customer. I'll keep you posted if we need any further support.

Best regards,

Jonathan

Hi Charles,

I have an update from the customer.

They are not referring to the CMSIS-DSP lib, they need is the CMSIS-Core files, namely
1. System Configuration Files system_<Device>.c and system_<Device>.h
2. Device Header File <Device.h>
3. Startup File startup_<Device>.c
4. Scatter-Loading description file <device>_ac6.sct
5. TrustZone setup: partition_<Device>.h
6. Region/ISR setup: partition_gen.h

Thank you for your usual support.

Best regards,

Jonathan

Hi Jonathan,

  I don't know what exactly these files you are referring to. I tend to think the files you refer are not really needed. If you can bring up a simple TivaWare example like hello or blinky you would already see the necessary startup file and device configuration. For example, if you look at the hello example, you will see the startup_ccs.c file that contains the vector table and startup code. 

It is just a matter of including the header files in the hello.c example to properly reference APIs that are needed to initialize the clock and peripherals. See below snippet.

#include <stdint.h>
#include <stdio.h>

Please follow the app note as mentioned in my last reply.

There is also a CMSIS example for MSP432E MCU which you can find in Resource Explorer.
