Pysense 2 with GPy: failed to get prompt
-
@Edward-Johnstone Does anyone know where to get a previous version of the firmware for the Pysense 2. Currently I've flashed it with pysense2_v16.dfu .. see below

@Edward-Johnstone Here is a similar post, though 2018, https://forum.pycom.io/topic/3596/pysense-not-working-with-lopy4/3, though there doesn't seem to be a fix here for me :(

Dear Edward,
I will be discussing this situation with our teams and provide you an information accordingly.
Have a nice one,
-
@Yusuf-BAYLAV thanks .... I have another one arriving today or tomorrow, I'm interested in attaching the GPy before and then after I upgrade the firmware on the Pysense 2. The first one I just flashed it as soon as I got it. It will be interesting to know if the next one that is arriving soon works before, but not after, upgrading the firmware.

@Edward-Johnstone The second Pysense 2 arrived today. It worked with the GPy "out of the box". Then I updated the firmware (see below) and it continues to work. This leads me to believe that the failure with the first Pysense 2 that I purchased was not caused by the firmware upgrade that I did. I still have no clue why the first Pysense 2 board is not responding - maybe just a bad board?

They immediately credited my account and did not require me to send the bad board back! Nice!!
Note, again: I suppose if you have a previous firmware I can try that, but beyond that I'm willing to assume it was just a bad board - unless you have other ideas. -
@Edward-Johnstone Hello, sorry with what you are facing. As all the boards a tested before having shipped this may be a rare situation. I doubt that may be affected from something peripheral. Anyways, we will investigate and try to come to you with a solution. It is just the beginning of the week, and you are on the queue.
Thanks,
-
@Yusuf-BAYLAV okay, thanks, ... it will be interesting if I can revive it : )

@Edward-Johnstone Hello again Edward.
There is one way of testing, to prove that your board is alive or damaged.
You may take apart your development module from the expansion board; short TX and RX pins with the help of a cable.If you see an echo back from the serial console (whatever you type) that means the board is alive. Otherwise, there must be an unfortunate damage.
Best,
Yusuf -
@Yusuf-BAYLAV Woo Hoo!! the terminal echo back what I typed. Now, .... what's the next step? (Thank you)
-
You are welcome. :) Now we need to get back to the problem. It may be stuck on a mode somehow. I will investigate this, talk to my friends and try to get back to you within next week.
