Other Parts Discussed in Thread: TCAN4550-Q1, LAUNCHXL-F28379D, EK-TM4C1294XL, TPS7B7702-Q1
I followed the instructions in "Connecting the TCAN4550-Q1 to the MSP430 - CAN/LIN booster pack" (https://www.youtube.com/watch?v=Ab1m_bUUeGs). In the video which has what appears to be the Texas Instruments logo, he says to "simply push them together" and makes no mention of the J11 and J12 but has the J12 (5vdc) only removed. He then says to connect the USB cable to the LanchPad but doesn't say anything about removing the shunts from the MPU board either. Eventually the two SPI to CAN FD SBC + LIN BoosterPacks regulators apparently overheated and over-voltaged the BoostPacks and LAUNCHXL-F28379D and EK-TM4C1294XL. This caused all four to fail in different area like the SPI and power circuits and and desktop USB which recovered after a reboot.
I subsequently reread the SLLU216–July 2019 - SPI to CAN FD SBC + LIN Transceiver BoosterPack User's Guide, and found the CAUTION notice in the "2.1.4 TPS7B7702-Q1 (External LDO)" section. I would recommend placing it earlier on in section 2.1 and adding notes to that effect as part of the Figure 2. Also that the jumpers not be pre-installed and that it be the customer's option to install them if desired.
I was following the video instructions am trying to get TI to replace two SPI to CAN FD SBC + LIN BoosterPacks at no charge but they are directing me to you. Please let me know what you think.
