SK-TDA4VM: Demo board pinmux or Sysconfig file

Randy St. John

Part Number: SK-TDA4VM
Other Parts Discussed in Thread: SYSCONFIG, TDA4VM

Tool/software:

We have several SK-TDA4VM Edge AI Kit demo boards and are working on one of the R5 processors. Comparing the Demo board's documentation (SK-TDA4VM users Guide (Rev.D) spruj21d.pdf) we can find no corresponding pin mux file for the demo board. It seems like all the pinmux files are for the J721e eval board wich has different pinouts.

So is there a ready made Sysconfig or pinmux c file for this demobaord or do we have to make our own?

Hi Randy,

Take a look at this E2E thread: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1273335/sk-tda4vm-is-pinmux-sysconfig-available

Please let me know if you have any further questions.

Thank you,

Fabiana

Ok, I got the file from that thread. I am still not sure it is correct for the SK-TDA4VM as it is named J721e_sk.pinmux. My understanding is that the TDA4VM demo board is a different board then the J721e demo board. Is there a reason this file is not named TDA4VM_sk.pinmux?

But..... I got to say I am dissapointed in TI that this file, or a newer Sysconfig file is not available from the Demo board downloads or linked somewhere.

How is anyone supposed to use the demo board if the software you download for it is for a different demo baord, J721e-evm?

So I think I got my answer from one of the other similiar questions.

We probably should have bought a different demo board for quicker RTOS development.

Hi Randy,

The SK-TDA4VM device only supports the Edge AI Linux SDK. For RTOS development, I would recommend you use TDA4VM EVM, not SK.

Thank you,
