I'm using MSP430G2553 platform ubuntu 20.04
ls -l /dev/serial/by-id
then I get
lrwxrwxrwx 1 root root 13 7月 1 20:51 usb-Texas_Instruments_MSP_Tools_Driver_721F896E22000100-if00 -> ../../ttyACM0
lrwxrwxrwx 1 root root 13 7月 1 20:51 usb-Texas_Instruments_MSP_Tools_Driver_721F896E22000100-if02 -> ../../ttyACM1
so I use the command
python msptool.py -f blinky.txt -p /dev/ttyACM0
but it not worked
msptool v0.3
Executing: ./mspdebug/mspdebug rom-bsl -d /dev/ttyACM0 "prog blinky.txt"

Could you tell me how to connect? Thank you
Hey @chenboshuo,
Please share the output of $ lsusb after connecting the USB-UART bridge.
and I tried
python msptool.py -f blinky.txt -p /dev/ttyACM1
/dev/ttyACM1 would be something like /dev/ttyUSB0 for the USB to UART bridge.
After getting the correct port follow the connection diagram available in the repository. Check if you have correctly connected the RST and DTR of the USB-UART bridge to the MSP430G2553 MCU.
Please share the output of $ lsusb after connecting the USB-UART bridge. The output is

In the mainstream manual,
they use /dev/ttyUSB0,
but I don't have it,
when I type
ls /dev/tty*
I get
/dev/tty /dev/tty21 /dev/tty35 /dev/tty49 /dev/tty62 /dev/ttyS15 /dev/ttyS29
/dev/tty0 /dev/tty22 /dev/tty36 /dev/tty5 /dev/tty63 /dev/ttyS16 /dev/ttyS3

/dev/tty11 /dev/tty25 /dev/tty39 /dev/tty52 /dev/tty9 /dev/ttyS19 /dev/ttyS4
/dev/tty12 /dev/tty26 /dev/tty4 /dev/tty53 /dev/ttyACM0 /dev/ttyS2 /dev/ttyS5

/dev/tty14 /dev/tty28 /dev/tty41 /dev/tty55 /dev/ttyprintk /dev/ttyS21 /dev/ttyS7
/dev/tty15 /dev/tty29 /dev/tty42 /dev/tty56 /dev/ttyS0 /dev/ttyS22 /dev/ttyS8
/dev/tty16 /dev/tty3 /dev/tty43 /dev/tty57 /dev/ttyS1 /dev/ttyS23 /dev/ttyS9
/dev/tty17 /dev/tty30 /dev/tty44 /dev/tty58 /dev/ttyS10 /dev/ttyS24
/dev/tty18 /dev/tty31 /dev/tty45 /dev/tty59 /dev/ttyS11 /dev/ttyS25
/dev/tty19 /dev/tty32 /dev/tty46 /dev/tty6 /dev/ttyS12 /dev/ttyS26
/dev/tty2 /dev/tty33 /dev/tty47 /dev/tty60 /dev/ttyS13 /dev/ttyS27
/dev/tty20 /dev/tty34 /dev/tty48 /dev/tty61 /dev/ttyS14 /dev/ttyS28
So I use this command
ls -l /dev/serial/by-id
