Airlift Firmware update

Post by Giv »

Hi,
I recently purchased two Airlift Breakout and read on its Web page to update the Firmware to (NINA_W102-1.7.4). So I Did that and I have the following output from it. I like to make sure the (Bold, Italic) Warning message below is just that and there is no issues with the update and the Airlift should be functioning withouit any issues.
See below;

\AppData\Roaming\Python\Python39\site-packages> python.exe -u -m esptool --port COM11 --before no_reset --baud 2400 write_flash 0 S:\Downloads\NINA_W102-1.7.4.bin

This is just a WARNING and probably a non-issue, but if you are comfortable opening an issue here maybe we can get some further confirmation or a fix.

Hi,

Thank you so much for your response. I just had to make sure that firmware update took 100% and there is no issue.

Regards.

Maybe because you specified baud at 2400 so the clk had to adjust far below what it normally expects for serial communication? I mean you should be using baud rate 115200. Try running it again at higher baud rate. If you’re still getting that specific error while flashing no matter the baud then it could indicate a crystal problem.

Is there a specific reason you chose 2400? 9600 is usually as low as you’d want to go for debugging. When it comes to erasing flash you’re only really limited in speed by the speed of the flash chip… which is like above 300k depending on the chip.

Hi,

The connections were made on a breadboard with jumper wires and the higher baud rate caused too much noise and it was failinig. I read to lower the baud rate to reduce the noise so I chose 2400, which didn't take much time to upload.

If I end up tryiing it again, I'll start with higher baud rate next time.
Thank you for your input.
