Other Parts Discussed in Thread: TMUX1574, TPS65988,
Tool/software:
Hi,
We have an application of TPS65988DK which configuration come from SPI flash. In this product, we add a SPI analog switch (TMUX1574) for upgrade FW online, when we need to update FW, we will switch TMUX1574, let the flash connect to CPU, and write new bin in it. In normal working, the SPI flash connect to TPS65988 by default.
Now we face a update problem. New bin file has already write to the SPI flash, but even I set reset for TPS65988 - pull high pin44, it doesn't reload the new bin. We have got to power off it. But it is not only power supply by VIN_3V3, but also power supply come from VBUS1 & VBUS2, we don't want to plug off USB-C port, that is mean VBUS1 / VBUS2 is always on, we can only power off VIN_3V3, how can we do for making the new bin work?
