MSP430I2020: MSPFlasher Verification failed - unable to flash device

Part Number: MSP430I2020
Other Parts Discussed in Thread: UNIFLASH, MSP430I2040, CCSTUDIO, MSP-FET

hello

i'm trying to flash an MSP430i2020 (and MSP430i2040) but keep getting 'verification failed' when flashing with ccstudio and uniflash
* ccstudio V12
* example blink (via new project.. no changes where made)
* pcb is breadboard with mcu soldered on an adapter board for TSOP28

wat are the minimal requirements (shema) for flashing this mcu via SBW and MSP-FET

current connections
VCC    - 10uF and 0.1uF to GND
AVSS - GND
ROSC - GND
DVSS - GND

RST/SBWTDIO - 47k to VCC and 1nF to GND

connection to MSF-FET
1. TDO/TDI      -- RST/SBWTDIO
2. VCC_TOOL -- VCC
5. TMS             -- TEST/SBWTCK
7. GND            -- GND

any feedback is helpfull, i've already designed a pcb but would like to make sure the design is programmable

I think you can try to use no verification setting. I think there may be something wrong with the code in MCU.

Hello Eason

thank you for the resosponse but unfortunately that did not help

i already tried flashing without verification followed by reading the flash

the result was all FFFF in the target memory

could you please confirm that the above mentioned connections are sufficient for programming ? (it's from the datasheet)
later today i will try to flash the device using JTAG instead of SBW

i've also ordered a few proto's of the design, maybe the issue is with the not so ideal connections on a breadboard

It seems not right.

sorry i did connect 7(SBWTCK) and 9(GND) not 5 and 7

i will wait for the pcb to arrive and test again, as it seems that the connections are correct thx

OK. I would suggest you change another new MSP430 and make a try.

When I used to meet this problem, I can use disable verification to solve it.

hello Eason

thanks for the support, the real proto boards arrived today and programming +verification is successfull !

i think the problems i had where with the breadboard and wires
all smd pcb is working fine !
