Hello E2E community,
TI recently discovered an issue with the LAUNCHXL-F28379D LaunchPad. This issue affects all LaunchPads marked VER: 1.1 and impacts the ability to utilize all of the available ADC channels.
The affected LaunchPads has ADCINA2 shorted to VREFHIB. This error was caused by a via intersecting a trace. It is recommended that users avoid using ADCINA2.
Additionally, manufacturing tolerance variation may cause a short between U1.VIN+ and ADCINB4 or ADCINC4. No issues have been reported on actual hardware, but it is worth noting in case odd behavior is observed.
These errors will be corrected in a future revision of the LaunchPad. Also, additional modifications to the board design will provide a more flexible evaluation platform for the user. We apologize for any inconvenience this may have caused. Thank you for evaluating our TMS320F28379D MCU!

In reply to Mark Labbato:
Is this issue may affect all the adc channels of the launchpad, or just A2, B4, C4 ?
