Not able to flash JN51XX chip

[galizki]

Hi, thank you for you efforts to bring this project to live, it is really great!

However, after installing OpenLumi within full soldering via UART + USB and installing 'Version 19.07.7 2021-02-24' I am having the issue with updating firmware JN51XX Zigbee chip.

The reason why I am trying to update the firmware is that I have not done it before installing zigbee2mqtt and failed to make it receiving commands from Ikea Zigbee devices , however all xiaomi buttons and sensors worked just fine. I assume that it is because I have not updated the firmware of the JN51XX chip and it is how the story begins..

If I launch firmware update within web interface, by filling in the URL and clicking OK, i got:

Flash /tmp/firmware.bin

I am getting the same result by entering the command manually in the console:

I have also played with another options to flash JS51XX and only the following gives another result (but it is also failed):

root@XiaomiGateway:~# jnprogrammer -v -s /dev/ttymxc1  -I 115200 -P 115200 -f ./zigate_JN5169_115200_31e.bin

I have also tried soft_reset and erase_pdm options of jntool and it does not help.

I am not sure if this issue related exactly to openlumi, but I really do not understand where the problem is. Please please advice.

It seems your zigbee port is busy. Stop zigbee2mqtt or any other software that may open and block the port and try again.

Thank you for your help! Launching /etc/init.d/zigbee2mqtt stop helped to resolve the flashing issue.

It is still issues with capturing commands from Ikea controls, but this question is out of this topic. Thanks a lot.
