SPRUJ63A September 2022 – October 2023
Applicable EVM Revisions: C
Issue Description: Many cost-saving plug designs do not verify a secure, ground-first connection when attempting to hot-plug the J6 DC Barrel Jack connector. This can lead to intermittent brown-out type conditions that can result in damage to the board.
Solution: Hot plugging the power supply is never recommended at the connector end. The Power On/Off Procedures outlined in the Getting Started section of the document must be followed when applying or removing power from the board. Furthermore, make sure the user is using the recommended part number for the EVM Revision as outlined in the Power Supply section of Section 3.1.
