CCS/TMS320F28379S: Trouble Setting Breakpoint with the Action "Remain Halted" at 0xc0eb: (Error -1066 @ 0xC0EB) Unable to set/clear requested breakpoint.

Part Number: TMS320F28379S


Tool/software: Code Composer Studio

Dear Ti Forum,

we have a brand-new design with a TMS320F28379S processor on it. Now we are trying to get it working, but we have troubles to flash the processor with the XDS100V3 debugger.

Interesting: watching and setting the registers with "load symbols only" works, but "Load program" always leads to the same error message: 

C28xx_CPU1: GEL Output:
Memory Map Initialization Complete
C28xx_CPU1: Trouble Setting Breakpoint with the Action "Remain Halted" at 0xc0eb: (Error -1066 @ 0xC0EB) Unable to set/clear requested breakpoint. Verify that the breakpoint address is in valid memory. (Emulation package 8.4.0.00006)
C28xx_CPU1: Breakpoint Manager: Retrying with a AET breakpoint
C28xx_CPU1: Error executing PLL configuration algorithm. Operation cancelled. (0x0)
C28xx_CPU1: File Loader: Memory write failed: Unknown error
C28xx_CPU1: GEL: File: C:\Users\emp001118\workspace_v9\Heater_brd_IBN\Debug\Heater_brd_IBN.out: Load failed.

Any ideas?

We are using CCS 9.3.0.00012
