Other Parts Discussed in Thread: MSP-FET
Tool/software:
I tried to debug MSP430F478 using SBW interface.
Below is the connection I made according to "MSP430 Hardware Tools User's Guide (Rev. AH)"
MSP-FET MSP
1 TDO/TDI -------- 74 nRST/NMI
2 VCC_TOOL -------- 1, 80 DVCC
7 TCK -------- 73 TCK
9 GND -------- 7,10 GND
TCK pin is pulled down by 5k resistor.
TDI/TDI pin is pulled up by 47k resistor and 2.2 nF capacitor which is connected to GND.
It didn't work, the device couldn't be found, CCS showed error message "Unknown device".
I modified the connection based on my former experience in other MSP430 controllers, but all those didn't work.
Below two are my modifications.
MSP-FET MSP
1 TDO/TDI -------- 70 TDO/TDI
2 VCC_TOOL -------- 1, 80 DVCC
7 TCK -------- 73 TCK
9 GND -------- 7,10 GND
MSP-FET MSP
1 TDO/TDI -------- 70 TDO/TDI
2 VCC_TOOL -------- 1, 80 DVCC
7 TCK -------- 71 TCI/TCLK
9 GND -------- 7,10 GND
How can I properly wire for SBW?
Or is SBW interface impossible for MSP430F478?
I double checked if I soldered properly but there wasn't any problem.
