Part Number:MSP430F5438A
I am unable to establish UART communications with the MSP430F5438A using BSL mode with BSL Scripter 3.4.0. I'm using the FET generation 1 (no CET label).
I'm using the BSLScripter_3.4.0\ScriptExampleWindows\Flash_OpenJtag\script.txt modified for my setup as follows:
MODE msp430f543x UART COM44
VERBOSE
MASS_ERASE
RX_PASSWORD
RX_DATA_BLOCK JTAG_UNLOCK.txt
I've tried to MODE msp430f5xx UART 9600 COM44, with same result. COM44 is the MSP Application UART1 as determined using step in SLAU655F page 37.
The scripter attempts to enter the BSL mode and sends data, but I get no response from the processor. Signals are getting to the processor as far as I can tell by doing a continuity test from FET pins to traces on the board near processor. Since it's a BGA part, I am unable to probe the processor pin. Voltage levels on the board look nice and clean 3.3 V.
Per the datasheet processor Pin1.1 is BSL_RX gets connected to FET pin 14, Pin 1.2 is BSL_TX connects to FET pin 12. The connections are similar in manner to the example described in SLAU655F.
Here are the scope captures of the reset and test timing to enter BSL.
Here is the first set of serial data sent:
Can you please provide tips/recommendations to get BSL working?
