TTGO (Lilygo) T-Display - ERRORS

[angelonardone]

I'm using the config file called "sdkconfig_display_ttgo_tdisplay.defaults" as the configuration file. I have the TTGO T-Display hardware .

when building the "firmware" an executing the idf.py flash monitor, in my case as idf.py -p /dev/cu.usbserial-57060042761 flash monitor I get the following errors:

Any Idea what could be the problem?

Looks like some problem with the esp-idf nimble/bt component... Is your esp-idf toolchain definitely installed, the correct version, definitely up to date, etc ?

If so, the repo should build for t-display without issue.

1. clone the repo, checkout tag (eg 1.0.31) or master and ensure submodules up-to-date with: git submodule update --init --recursive
2. remove any old/stale build artifacts with: rm -fr sdkconfig build managed_components
3. copy the t-display config defaults: cp configs/sdkconfig_display_ttgo_tdisplay.defaults ./sdkconfig.defaults
4. build! idf.py all (or idf.py all flash monitor if you want to go the whole hog)

This should work without error.

Not heard back, presumed resolved. Please reopen with more details if still having problems building the firmware. Many thanks.
