Lgt8f328p with Platformio and VSCode - unknown platform

fittyfu · August 3, 2023, 6:23pm

I can no longer compile my projects for LGT8F because of the “platform” is unknown.
Following output is generated after I deleted “,platformio/platforms/lgt8f” directory and tried to compile the project:

The problem started after I tried to update the LGT8F environment, because an empty “sketch” used up more than 26K of program memory???

maxgerhardt · August 3, 2023, 6:37pm

The problem is not reproducable for me.

Doing, on the CLI

pio pkg install -g -p "https://github.com/darkautism/pio-lgt8fx.git"
mkdir green
cd green
pio init -b LGT8F328P
notepad src\main.cpp
# < add blank sketch, save and close>
pio run

gives

I’d advise you to just reinstall.

Close VSCode
Delete C:\Users\MiKo\.platformio
Reopen VSCode
Wait for automatic reinstallation

fittyfu · August 4, 2023, 8:47am

Sorry …
When I was talking about empty sketch, I was thinking on an empty arduino sketch - only including arduino.h.

Like this:

#include <Arduino.h>
void setup() {
// setup
}
void loop() {
// loop
}

fittyfu · August 4, 2023, 8:55am

I followed your advise, closed VSCode, deleted “.platformio” directory, and started VSCode again.

But have the same result, trying to compile for LGT8F:

The there appeared another error message:

pio_error

I think that is not new, but I ignored the message …

maxgerhardt · August 4, 2023, 8:57am

I used the same.

Try the exact platformio.ini

[env:LGT8F328P]
platform = lgt8f
board = LGT8F328P
framework = arduino

fittyfu · August 4, 2023, 9:04am

sorry, same problem …

maxgerhardt · August 4, 2023, 9:06am

Please open a CLI and

pio upgrade
pio pkg install -g -p "https://github.com/darkautism/pio-lgt8fx.git"

Then Ctrl+Shift+P → Reload Window and try building again.

fittyfu · August 4, 2023, 9:17am

same problem when compiling (didn’t take new screenshot)

maxgerhardt · August 4, 2023, 9:23am

I’m absolutely baffled here, I have the exact same PlatformIO core version installed.

Can you change the platformio.ini to

[env:LGT8F328P]
platform = https://github.com/darkautism/pio-lgt8fx.git
board = LGT8F328P
framework = arduino

Then repeat these steps

fittyfu · August 4, 2023, 10:29am

First off all, many thanks for your great support!

All problems seems to be fixed and the memory “problem” must be my fault.
Was surprised that this little project (radiohead, bmp280, Si7021) already used up all memory:

Thank you very much!

maxgerhardt · August 4, 2023, 10:29am

Okay so now it seems you’re able to compile regular sketches (empty ones at least) again. Can’t tell much about your full sketch, but the list of included libraries and the application code may indeed legimately exceed the flash capacity of the chip. You may be able to check the memory usage using this.

fittyfu · August 4, 2023, 10:46am

Nice! I’ll check this …

I’ve copied the complete code, that already exceeds the available memory - while several things are not even integrated now, like deep sleep, …

There is another problem - I cant communicte with the LoRa module (RFM95W) on SPI bus.
Permanently getting error -2 (not connected), while the same code works for RFM95W with WEMOS D1 mini Pro.

Is there something special with the SPI bus on LGT8F?

fittyfu · August 5, 2023, 8:33am

Inspection breaks early at memory check (about 10%):

maxgerhardt · August 5, 2023, 10:58am

Welp, not a lot of error message to go on here

In any case though, in your previous full sketch, it seems like it does generate the .elf file and then just fails in the post checks (because the full 32K is not available due to a boodloader I assume). Which means you should be able to do the following:

Let GCC generate a map file (Generate a .map file - #8 by Krishna_Chaitanya)
throw that in amap.

pixelwaster · August 6, 2023, 4:25am

Just a side note, “framework-lgt8fx @ 1.0.6” is over 3 years old. They did work on SPI, low power, and more. 2.0.6 is the current release for use with Arduino IDE. . GitHub - dbuezas/lgt8fx: Board Package for Logic Green LGT8F328P LGT8F328D and LGT8F88D
Tried to make a framework but never could get it to work. Might take another run at the docs and try again.
Sorry fir the interruption.

<edit: typos>

fittyfu · August 6, 2023, 11:31am

Yes, same here.
Trying to update to 2.0.6 will have been the reason for my problems, leading to this topic …

Do you have a link for where to start?

maxgerhardt · August 6, 2023, 11:36am

This answer is correct in terms of upgrading: https://github.com/dbuezas/lgt8fx/issues/15#issuecomment-751517482

Basically, download https://github.com/dbuezas/lgt8fx/blob/master/lgt8f-2.0.6.zip, add package.json to the core’s root, point to it using platform_packages and the symlink:// protocol. You can also reupoad that 2.0.6 version with the package.json to Github to enable you to use a Github link instead.

fittyfu · August 6, 2023, 12:16pm

I’ll try this later, because the code is not nearly complete, so will just need more flash or other (own?) libs.
Changed from radiohead lib to the outdated LoraLib reduced the amount of used flash to 64,9% (from 101,8% ).

I’ll try this …

How would a “platformio.ini” look like, with platform_packages and the symlink:// pointing to a local directory?

maxgerhardt · August 6, 2023, 12:18pm

I would look like the documentation says.

platform_packages = 
   framework-arduino-avr-lgt8f@symlink://C:\Users\SomeUser\Desktop\lgt8f-2.0.6\lgt8f
