TMS320F28375D: Uniflash programming sometimes fails with unable to set breakpoint error

Part Number: TMS320F28375D
Other Parts Discussed in Thread: UNIFLASH

Hello C2000 team,

I have a customer who is trying to program the TMS320F28375D in a production environment, and they're experiencing an intermittent issue where programming will fail, or take longer than the expected ~13 seconds to complete.

Devices which initially fail programming usually pass the second time, and not all devices experience this issue, but obviously it would be preferable to have all devices pass programming the first time.

Uniflash 5.1 shows the following error message:

Loading Program: C:\fwcore1Pos1.out
Preparing ...
codestart: 0 of 4 at 0x80000
error: 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 8.2.0.00004)

warning: C28xx_CPU1: Breakpoint Manager: Retrying with a AET breakpoint
error: C28xx_CPU1: Error executing PLL configuration algorithm. Operation cancel
led. (0xAA55AA55)
error: C28xx_CPU1: File Loader: Memory write failed: Unknown error

Look forward to your suggestions!

Regards,

Munan
