I want to run the command FsciBootloader / dev / ttymxc5 /home/root/GwRadioFirmware/KW41Z/KW41Z-hostcontrol-serial-upgrade-v2.0.5.bin when the system is started for the first time. This command flashes another device via the data UART. I need to run the following command according to the success of this data transfer (flash).

/ usr / bin / ThreadDeviceMgr / dev / ttymxc5 fslthr0 0.

For this, I first created a bash file in the /etc/ file path and added

#! / Bin / bash
echo "stuttering is starting ...."
FsciBootloader / dev / ttymxc5 /home/root/GwRadioFirmware/KW41Z/KW41Z-hostcontrol-serial-upgrade-v2.0.5.bin
echo "write completed ...." 

I wrote the commands.

Next, I created a service script in the file path / lib / systemd / system and wrote the following commands.

[Unit]
Description=Thread network manager
After=gateway-config.service

[Service]
Type=simple
ExecStart=/etc/flashTTT.sh

[Install]
WantedBy=multi-user.target

Then, I created a second service file and in this service file I want to execute the following command according to the result of the command in the first service file and complete the operation.

[Unit]
Description=Thread network manager
After=thread-write.service

[Service]
Type=simple
ExecStart=/usr/bin/ThreadDeviceMgr /dev/ttymxc5 fslthr0 tap 0

[Install]
WantedBy=multi-user.target

1. Are the steps I have implemented correct?


2. How can I learn that the flashing process is successful?


3. 
   

   If I run the services according to the above steps, 2nd service does not start after the flashing and I get the following error.
