TMDS64GPEVM: Load & Debug PRU

Part Number: TMDS64GPEVM


I'm trying to load a program into a PRU. I managed it to run a program on the R5, using the supplied OSPI image (for loading DMSC firmware). When I try to load a program into the PRU, I end up with:

"Texas Instruments XDS110 USB Debug Probe/ICSS_G0_PRU_1 : Target must be connected before loading program."

So I tried to load manually. When I connect to the PRU, it tells "Connecting: In Reset". (The R5 always showed "connected")

I also tried to start with "No Boot", and the *.js script file. Here I got stuck earlier:

js:> loadjsfile "C:/ti/mcu_plus_sdk_am64x_07_03_02_01/tools/ccs_load/am64x_am243x/load_dmsc.js"
Connecting to DMSC_Cortex_M3_0!
Error evaluating "Init_M4()": 'Init_M4()' not found
at Init_M4() (C:\ti\mcu_plus_sdk_am64x_07_03_02_01\tools\ccs_load\am64x_am243x\load_dmsc.js#148

Any ideas?
