Other Parts Discussed in Thread: C2000-GANG
Hi team,
Here is a problem when my customer is trying to flash 4 chips with simultaneous with C2000 GANG.
1. All the 4 chips' power supply is from C2000 GANG, no external power.
2. When programing, there is a possibility that the targe VCC 'LED' in C2000 GANG GUI would turn to yellow while erasing the device. And a error was reported.
3. Try to programe again, the device cannot be connected and the error MCU device INT FAILED or MCU unlock error were reported.
4. Monitoring the 3.3V, a voltage some drop to 3.26V~3.27V, and a error may occur.
5. If 3.3V is supplied by an external DC power, the fault does not occur.
Any suggestion on this issue?
