Hi Team,
There is a issue from the customer need your help:
Can't connect control card, some error shows as below when debug, the oscilloscope collects XRS (F19 pin) and obtains a 140us low pulse, measures 3.3V, 1.2V voltage is normal, and usually XRS is high level (3.3v)
C28xx_CPU1: Error: (Error -1137 @ 0x0) Device is held in reset. Take the device out of reset, and retry the operation. (Emulation package 8.1.0.00005)
C28xx_CPU1: Unable to determine target status after 20 attempts
C28xx_CPU1: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging
C28xx_CPU1: Error occurred during flash operation: Could not read 0x0007026D@Data: target is not connected

Above is using CCS9, when i change to CCS11 the error changes to below:
C28xx_CPU1: Trouble Removing 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 9.7.0.00213)

C28xx_CPU1: Breakpoint Manager: Retrying with a AET breakpoint.
Could you help check this case?
Thanks and Regards,

It's the first time with new-designed card, testing 3.3V and 1.8V supply voltage are normal, ripple peak within 150mv; XDS100v3, xml configuration is normal. Self-designed card, emu0 emu1 pull-down with a 4.7k resistance, TRSTN 2.2k pull-down, tck frequency waveform is normal. During debugging, the waveform on xrs is monitored as shown in the figure below
emu0 emu1 pull-down with a 4.7k resistance,
Emu0 and EMU1 should be pulled up not down. Please correct and report back.
Hi Cody,
Sorry, I made a typing mistake, the emu0 and emu1 are pulled up.

Ben
Does XRSn remain high during communication? If it is being pulled low the debug probe will not be able to communicate with the C2000 device.
