MSP430FR5994: Facing issue with bootloader section of msp430fr5994

Part Number: MSP430FR5994

Hi TI Team,

I am using this document https://www.ti.com/lit/an/slaa760/slaa760.pdf for bootloader activity .
Here beagle bone is the host and msp430fr5994 is the target.
I have downloaded source code folder provided in document and I have taken blink_led example of msp430fr5994 in txt format and converted that into MSP430 FRAM firmware image using the python scripter as provided in the source code and placed that firmware image in the image folder of UART_BSL_MSP430FR.
Then I transferred UART_BSL_MSP430FR files to beagle bone board using pscp (putty) commands as mentioned in the document.
After that I build all the .c files in that folder using GCC commands and I got an executable file after building all these files.
I have made the pin connections between host and target as mentioned in document. After that when I am running it, the process is getting stopped. I have attached screenshot also.

If you can provide solution for this issue then it would really be helpful.

Can you use oscilloscope catch the UART wave?

I assume the BSL is not started.

Hi Eason,

I have already one loaded blinky code in msp430fr5994 eval board. When I am running that ./msp430fr_bsl command in putty, that led is going OFF. I am not not able to catch any wave in oscilloscope. It is always flat, No waveform is there.

Hi Abhisek,

So, it seems the code work. But you don't see anything from the UART, right?

Can you catch the wave on reset and test. That two pin is used to invoke BSL.

Hi Eason,

The code is getting stuck while running it in putty terminal. Only what I observed whatever blinky code was already loaded in the msp430fr5994 eval board. That blinking of led in eval board gets stopped as soon as I start the "./msp430" command in putty terminal.

You are right. Reset and test pins are used to invoke BSL. I will catch the wave of these 2 lines and let you know.

Hi eason.

Do you feel I need to make some change in the code?

Hi ,

While catching the wave while running the code, it seems the reset pin is always high and test pin is high for 200 ms and after that it will be always low.
