CCS/MSP430FR5994: DMA0CTL_L doesn't define in msp430.h

Part Number: MSP430FR5994

Tool/software: Code Composer Studio

Hi everyone,

Recently, I imported CTPL module to my project, but I found that it always fails to build due to the undefined "DMA0CTL_L" valuable in "ctpl_low_level_marcos.asm".

However, there's only "DMA0CTL" but no "DMA0CTL_L" in user guide.

Therefore, is there any possible that it's a typo or something I misunderstood ?

Please let me know if there's something I miss.

Thanks for your reading!

Best wishes,

Hi,

It should stand for low byte(bit[0:7]) of the DMA0CTL, since the instruction is clr.b

Hi Wei,

Thanks for your response.

Actually I'm just import CTPL module following by user guide.

First, it can't pass the compile due to the undefined DMA0CTL_L, so I modify it to DMA0CTL and pass the compile.

To my surprise, once I change DMA0CTL back to DMA0CTL_L in ctpl_low_level_macros.asm, it just pass the compile and can load to my launchpad.

Could you please tell me how to justify if the function I used is correct or not.

Thanks!

Best wishes,

Hi Wei,

Sorry for bothering you.

I just found that DMA0CTL_L is still unusable. Here is my error message

And my project configuration is:

It seems that ctpl_low_level has something wrong

Could you please help me solve this problem?

Thanks,

Hi Wei,

I've just found the solution on E2E

Sorry for bothering you so much!

The link is the solution https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/873667?tisearch=e2e-sitesearch&keymatch=ctpl

I find that it's indeed the mistake or typo, cause the solution just commit "clr.b DMA0CTL_L" and using "clr.w DMA0CTL".

If this really solve this issue, please update the package in official website http://www.ti.com/tool/MSP-FRAM-UTILITIES

Just in case other users will have same problem.

Best wishes,

Chouying Hsieh
