I use GPIO 34(MISO), GPIO33(MOSI), GPIO35(SCK), GPIO36(CS) for external SPI flash. Are you suggesting to share SPI between internal flash and external flash? Note that we are also using External RAM. As far as I know if I use external RAM and if I share external flash with internal flash, I might fa...

I am facing the similar problem with my LTE modem. I am trying to put ESP into automatic light sleep but it is simply not working with modem driver running.

Were you able to resolve it? May be we can share the idea.

Hello ESP developers, I connected external SPI flash (W25Q32JV) to ESP32S2. Standalone example just works fine on ESP32S2. I am able to read/write into file. I also connected SPI Ethernet (WIZ850io - W5500) to ESP32S2. Standalone example also works fine with ESP32S2. I am getting IP and able to ping...

I am using External Flash with ESP32S2 since 4 months. So far no problems but When I try to share that SPI bus with my SPI Ethernet, it does not work out of the box. Seems like I will have to link both flash and Ethernet driver to use the same SPI bus. Ideally It should work out of the box with some...

I am facing memory corruption while coredump and esp32s2 keeps on restarting on giving Cache Error. See below log for more information. To reproduce the issue, I have disabled watchdog feed for one task and after watchdog timeout, system aborted and tried to write to coredump into flash. While writi...
