TMS320F28379D: How to use etherCAT on CPU2?

?? ?

Part Number: TMS320F28379D
Other Parts Discussed in Thread: CONTROLSUITE

Tool/software:

Hello,

I am currently using the TMS320F28379D and trying to use EtherCAT on CPU2.
I have set the predefined configuration for CPU1 on CPU1 and the predefined configuration for CPU2 on CPU2.

I believe there are issues in the following three files:

etherCAT_slave_c28x_hal.c
F2837xD_Emif.c
F2837xD_GlobalVariableDefs.c

Upon reviewing the errors, I found that these files restrict access using #ifdef CPU1, making them available only for CPU1, preventing their use on CPU2.

Since I need to use EtherCAT on CPU2, I am looking for a way to make this possible.
If you have any insights or solutions, I would greatly appreciate your advice.

The relevant files are located at:
controlSUITE\development_kits\TMDSECATCND379D_V1.0\TMDSECATCNCD379D_PDI_HAL_API\pdi_hal_test_app\hal

Thank you!

Hi,

You will need to allocate the EMIF and ECAT stack code to run on CPU2. Note that only EMIF1 can be allocated to CPU1 and CPU2, while EMIF2 can only be allocated to CPU1.

Best,

Kevin

So, in the end, I won’t be able to use the functions mentioned above, and I’ll have to rewrite everything from scratch, right?

I see there is code for EMIF1 and EMIF2 in the files. I imagine much of the code can be re-used for CPU2 usage.

Best,

Kevin
