mspdebug with generic USB-UART bridge to program MSP420G2553

[lorforlinux]

Hi, I was working to port BSLDemo2.exe to Linux but facing some problems.

I was wondering if it's possible to use the mspdebug tool with the generic USB-UART bridges like CP2102, CH340, PL2303, and FT232R to program MSP430G2553?

Yes, MSPDebug supports the bootstrap loader. You will need to ensure that the two control pins used for entry are attached to DTR/RTS, and perhaps specify the correct entry sequence on the command-line (see --bsl-entry-sequence).

Hey @dlbeer, Thank you for the info. I got access to MSP430G2553 with FT232RL using mspdebug rom-bsl -d /dev/ttyUSB0 and I am able to program it with the prog command in the mspdebug console. Now, I want to program the chip with file name within the command itself. I am not able to figure out how to send the file in the command itself. I tried doing mspdebug rom-bsl -d /dev/ttyUSB0 blinky.txt and multiple other variations but it's not working, please let me know how to achieve this functionality.

I can not express how happy I am after seeing the mspdebug console, I worked so hard to reinvent the wheel and ignored this wonderful car you made. You and all the mspdebug contributors are awesome, thank you so much for this wonderful tool.

Glad you like it!

Try:

mspdebug rom-bsl -d /dev/ttyUSB0 "prog blinky.txt"

Remember the quotes.

Hi @dlbeer, do we have an executable release of the mspdebug for windows? I am not able to compile it, getting these errors:

process_begin: CreateProcess(NULL, pkg-config --cflags libusb, ...) failed.
Makefile:53: pipe: Bad file descriptor
process_begin: CreateProcess(NULL, pkg-config --libs libusb, ...) failed.

The Makefile may have been broken a bit since it was last tested on Windows. Try this:

make CC=gcc

Thanks, @dlbeer for the help 👍 I did the following to compile it on windows,

This is what we have now,

CC ?= gcc
....
....
    ifneq (, $findstring(MINGW, $(UNAME_S)))
        PORTS_CFLAGS := $(shell pkg-config --cflags libusb)
        PORTS_LDFLAGS := $(shell pkg-config --libs libusb)
        RM = rm -rf
    endif
....
....

I replaced it with this,

CC = gcc # removed ?
....
....
    ifneq (, $findstring(MINGW, $(UNAME_S)))
        PORTS_CFLAGS := $(pkg-config --cflags libusb) # removed shell
        PORTS_LDFLAGS := $(pkg-config --libs libusb) # removed shell
        RM = rm -rf
    endif
....
....

for the execution I copied some dll file from energia's mspdebug folder and some as described here and it worked!

I have created a new flashing tool called msptool for flashing MSP430G2xx3 using your awesome tool. This allows us to create an Arduino-like board based on the famous MSP430G2553 with Energia support!
