Part Number: MSP430FR5043
Other Parts Discussed in Thread: MSP430FR6989

Hi,

I'm currently working on MSP430FR5043.

I need to upload my program using UART bootloader for example : LED blinking. (using UART bridge CP210x)

Here the issue is I'm getting error ack.

For script file I used /ScriptExampleWindows/FRxx_uart/script_FRxx_uart.txt file in BSl_scripter package

the default script is for MSP430FR6989. Considering the controller I'm using is MSP430FRxx family

the only thing I changed is COM port which is COM3 and program file ledblink.txt.

Below is the response I'm getting.

What would be the issue here connected pins

TX RX

DTR - RST/NMI

RTS - TEST

Thanks in advance.

Hi,

Do you have access to an oscope or logic analyzer? It will be necessary to view the wave forms for TX, RX, RST, and TEST to debug this.

I'm not sure if BSLScripter will support CP210x without customization. BSLScripter has a custom communication protocol (which involves changing the baud rate) that triggers the BSL invoke.

If you need to use BSL with CP210x you may refer to https://web.archive.org/web/20210812170601/https://forum.43oh.com/topic/13429-modified-bsl-scripter-for-windows-now-works-with-ftdi-and-other-usb-to-uart-adapters/

Regards,

Evan

Thanks for your response,

The URL for CP210x BSL is not found and error.

any other reference, if not can you guide me how to use MSP - FET for UART BSL.

either for MSP430FR5043 or MSP430FR6989

Hi,

Certainly! The best resource is:

MSP430 FRAM Devices Bootloader (BSL)

Please reply if you have any additional questions.

Evan

Okay ,

Other than CP210x

what are the uart devices I can use for BSL scripter?

Also I have MSP - FET

MSPFET will definitely work with BSL scripter. I'm not sure of others UART devices that are compatible out of the box.

okay,

pin connection I gave is

Controller MSP- FET

P2.0(TX) 14(RX)

P2.1 (RX) 12(TX)

RST 11(RST)

TEST 8(TEST)

Vcc 4(VCC)

Gnd 9(GND)

Is this enough

Double check your MSPFET connection for TX and RX. MSPFET is actually labeled with the target naming so MSPFET TX should connect to target TX.
