MCU-PLUS-SDK-AM263X: AM263X_CC Multicore

Vladyslav Prudius

Hello,

I'm trying to run multicore projects on two cores of AMX263_CC and getting the error with Core1.

For reproducing please try to complete the below steps:
1. Create a new system project for AM263x_CC
2. Create two new projects and assign them to corresponding cores
3. Build them
4. Run the CCS debugger

Best wishes,

Vladyslav Prudius

Hi Zain Nasir,

Can you resend the image ?
Also what is your current boot mode of the device ? - https://software-dl.ti.com/mcu-plus-sdk/esd/AM263X/latest/exports/docs/api_guide_am263x/EVM_SETUP_PAGE.html
Checkout this https://software-dl.ti.com/mcu-plus-sdk/esd/AM263X/latest/exports/docs/api_guide_am263x/CCS_LAUNCH_PAGE.html -

Hope it helps.

Hello, in my previous answer I did not send any images. I just sent this link: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/502679/error--1170-unable-to-access-the-dap This is an old thread that discussed about the same error message that you are seeing. I thought that you may find some solutions from this thread.

Hi Zain Nasir,

Are you using XDS debugger from TI or is this some other debugger ?

Hello Zain,

It appears that you are operating in lockstep mode and trying to access core1 of the first R5F cluster. You can only connect to core1 in dual core mode. Within CCS, you can run the diagnostic script shown below after connecting to core0.

Within the UART Console it will print if the R5FSS is in dual core or lock step mode.

If it is in dual core mode then core1 can be connected to:

Erik
