SK-AM64: First steps to debugging state

Part Number: SK-AM64

Hi TI.

The issue is to make the board debuggable on CCS v10.3.1.00003.

First steps:

- Power sequence: 5V, 3A: LD2, LD14, LD16 - green, passed;

- Debug probe connection (JTAG, cJTAG) from PC to emulator, 5.5MHz - passed;

- Start bootable SD card (tisdk-default-image-am64xx-evm.wic, boot config B15-B0: 00010010 01000011) image  - failed;

- Actual debug session on CCS - failed.

Error connecting to the target:
(Error -2081 - (0:0:0))
Device functional clock appears to be off. Power-cycle the board. If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 9.3.0.00058)

Thanks,

Alexey

    Solved:

    Linking debug probe to processor was done succesfully on different "boot/no-boot" modes using EVM setup instructions (Launch the target configuration) and connecting to M3 core first. Then GEL scritps automatically start power sequence and PLL for selected cores. All other processors (A53, R5, M4) are now fully avalable for debugging.

    Regards,

    Alexey.
