Hi, I’m new to the Platform IO Community. I have been using it with various MCUs but recently started using an EK-TM4C123GXL. I looked on Platform IO and found:
TI LaunchPad TM4C123 80MHz
MCU: LPTM4C1230C3PM
Flash: 256KB
RAM: 32KB
I was disappointed because I did not see the TM4C123GH6PM listed, but I figured I could make a pull request and add it myself. That’s when I noticed there does not seem to be a LaunchPad TM4C1230C3PM, just the MCU. Furthermore, the actual specs are Flash: 32KB SRAM: 12KB, which does not match the specs above. The product URL is given for the board on GitHub clearly states that the EK-TM4C123GXL uses the TM4C123GH6PM MCU (which does match the given specs), not the LPTM4C1230C3PM.

I decided to look through the pull requests and found one that addresses this exact issue, but it was closed without explanation.
https://github.com/platformio/platform-titiva/pull/8
So I am wondering is there a reason that the MCU is not what it should be, and if I make a pull request to fix this, what can I do to not have it closed like the one above.
I appreciate your help.
