Small number of early devices were shipped with improper configuration.
We’ve created a archive with the proper configuration and a flashing utility that can be downloaded here
Unpack the archive on the module and run this command:
./mxt-app -d i2c-dev:N-004a --load LTCTP070-3-GG_mXT1066T2_tdx_20170911.xcfg
Where N depends on the modules type:
- Colibri IMX7: N = 3
- Colibri IMX6: N = 2
- Colibri IMX6ULL N = 0
- Colibri T30: N = 1
- Colibri T20: N = 0
- Colibri VF: N = 0
- Apalis IMX6 N = 1
- Apalis T30: N = 0
after power cycling the board touch should work without issues and new config should be persistent across power-cycles and module changes.
