Re: Read from SPIFFS through http server handler results in Guru Meditation

The driver is initialized like this: rmt_driver_install(rmt_tx.channel, 0, ESP_INTR_FLAG_LOWMED | ESP_INTR_FLAG_IRAM | ESP_INTR_FLAG_SHARED) Onc...

Read from SPIFFS through http server handler results in Guru Meditation

I'm trying to read contents of a file on a SPIFFS partition from a HTTP server path handler which mostly results in a Guru Meditaion: Cache disabled but cached memory region accessed exception.

Re: Wifi not working on WROMM-32E but working on the WROOM-32

Hey ESP_Minatel, thanks for the hint about the issue. It looks similar but it's closed already and it didn't get solved.

I opened a ticket in the IDF repo on github: https://github.com/espressif/esp-idf/issues/6427

Wifi not working on WROMM-32E but working on the WROOM-32

Hey all, for some reason the minimal wifi station example is working on an older dev board with an ESP32-WRO)M-32 is working. However on my custom PCB with ESP32-WROOM-32E it is not. It's exactly the same software I'm flashing. On both boards, I first erased the flash via `idf.py erase_flash`. The d...
