Building firmware using PlatformIO

[Taylor Lee]

Hello,

I am trying to build firmware using PlatformIO but it keeps locking up, and I have to use recovery mode to fix it. I have put together a simple project based on wvr_basic.ino, and setup my .ini file as instructed in your readme.

I noticed that the build file out of VS is .bin. It seems all the firmware files need to be .ino.bin, and simply changing the name doesn't work?

Any idea what I may be missing?

Thanks!

[WVR Audio]

Hey sorry to hear that.

.bin is the correct extension. The Arduino IDE adds .ino.bin but it's not important.

Do you have a USB->FTDI module? It is highly recommended that you have one setup, otherwise there is no way to debug issues that come up when writing custom firmware. https://github.com/marchingband/wvr#setting-up-for-arduino-ide-programming

If you would like to link me to your code, I could try to identify possible issues.

Let me know any other ways I can support you in your firmware!

[Taylor Lee]

I really appreciate the quick response! 

I will hook up an FTDI cable and see what I can get out of the debug terminal. In the mean time I have attached my main.cpp.

[Taylor Lee]

I was able to connect my FTDI cable, and got the following output. This shows it first booting wvr_basic 3.8.0 successfully, and then it shows the loop I see when I run my firmware.

Great!

Set useFTDI = 1;

And the missing logs will print.

Also, do not reset or otherwise use D0 or D1 … those are the FTDI pins so you need to leave them alone for logging.

Enabled FTDI and I get te same printout, but now I am seeing the following at each reset;

Ok strange, I'll run some tests this morning. thanks for your patience and for the bug report.

[WVR Audio]

I commented out lines 85, 86, 91, 92, 97, 98, 103, 104, 105, 106 (everything for D0 and D1).

Then uploaded the firmware using the web UI.

I started the terminal with `pio device monitor`

and got this error log

The Backtrace is the part that will provide the stack trace, but it must be decoded.

in PIO this is done by adding 

build_type = debug

monitor_filters = esp32_exception_decoder

to the platform.ini

flashing this debug binary I get this extra log

As is sometimes the case, this wasn't particularly helpful information.

However I started commenting out other stuff to debug and spotrted the bug in your code

lines 97-101 you initialize Button in the the same variable multiple times.

it should be:

switchOne = new Button(D0, FALLING, 40);

switchTwo = new Button(D1, FALLING, 40);

switchThree = new Button(D2, FALLING, 40);

switchFour = new Button(D3, FALLING, 40);

switchFive = new Button(D4, FALLING, 40);

[Taylor Lee]

Thank you.

I am having another issue now, which maybe needs a new thread. I tried using the Arduino IDE to build my firmware and it corrupted things on the ESP32. I used the IDE to upload wvr_ftdi.ino over FTDI, but even after successfully loading it, the ESP32 cannot boot.

Here is the printout I see repeat.

This PIO toolchain is quite new to me, so do bare with me please.

I am also noticing an issue of some kind, where the WVR is flashed initially using Arduino CLI (when I manufacture them), subsequently uploading binaries produces with PIO seems to have an issue with some of the flash addresses for the debug dump ... I am not sure if it will cause problems, but, I would recommend running:

pio run -t upload

At 
at least once when you begin with a new WVR, using the instructions here: https://github.com/marchingband/wvr#using-ftdi

This means that PIO will upload all the contents of flash, not just the binary, and everything will be in its intended place in flash.

[WVR Audio]

Your problem on the Arduino IDE is indicated by these lines in the log:

Total PSRAM: 0
Free PSRAM: 0

You will need to tell the Arduino IDE that you are using a WROVER module, and that it has PSRAM

They keep changing exactly how that works, so I am not sure ATM, but let me know once you figure it out, and I will update the readme

[WVR Audio]

Anytime you change hardware settings, you will need to flash via FTDI, this information is not contained in the .bin file, so the full flash must be erased and written fresh, which is only possible vie FTDI

[Taylor Lee]

Yes! Thank you, you have fixed both issues.

 Sorry the original issue was just my bad code. Hopefully this post will at least be helpful for all the new Sparkfun users :P .

I really, really appreciate the quick help. This has been a life saver in a crunch.

[WVR Audio]

Awesome! No problem, I appreciate having someone run through the process. You may be the first user to build and use a custom binary, so congratulations!

[Taylor Lee]

Oh wow, I didn't expect to be the first. In that case, I am impressed it went so smoothly :P .

In appreciation of your wonderful support, I thought I should share a couple photos of the finished project.

This is for part of a product demonstration, where we need to see how a device responds to different audio inputs. The blue button just turns on a usb fan to simulate wind.

[Taylor Lee]

cnt.

[WVR Audio]

oh AMAZING 😍
Thank you so much!!

I should start a gallery soon, I have 4 or 5 decent build pix from various makers now :)
