I believe I have solved this although I am by no means an expert.. Originally I was running Let's Encrypt and certbot on the server to create and manage certificates. I've now turned off certbot so that it no longer manages the specific site that I am hosting firmware updates from. I'll have to self...

Hi, I have some esp32-s2's which are about a year old now. When they boot they report "esp32s2-rc4-20191025" and "This is esp32s2 chip with 1 CPU cores, WiFi, silicon revision 0, 4MB external flash". If someone has a more recently acquired esp are you seeing the same silicon revision etc. or have th...

Thanks Angus. Actually it's not resolved anymore. It's gone back to having the same problem even with everything updated. I'm trying to work out what's going on before posting an update. I'm doing everything I can to try and isolate this problem. It's a tricky one because it takes time for this prob...

Thanks - appreciate it.

That's a good idea. I'm still not sure how to search within a thread, or within one the front page topics.

I managed to fix this. It's pretty obscure and probably my mistake for not knowing how to update my tools correctly. I'm still not sure if I know to update my tools correctly to be honest, but the following worked and may help somebody. This all came from trying another computer which had a higher v...

I've got some esp32-s2's here which are now four or five months old (since I purchased them). When they boot they report in idf.py monitor "ESP-ROM:esp32s2-rc4-20191025". Could someone with a more recently acquired esp32-s2 let me know what more recent chips are reporting? Also is rc4 the final stab...

I'm trying to search these forums for things related to the esp32-s2 but the way the search function works doesn't seem to allow this. If I search a forum for esp32-s2 it searches for esp32 and ignores the -s2 part due to the way that a + means include and a - means exclude in the search function. I...

Hi Alvin, Thanks for replying. The following output from idf.py monitor seems to have most of the things you asked for. If there's anything else you need please tell me where to find it and I'll chase it down for you. Note this is the output from the unaltered spi_master lcd example code. It continu...

I'm working on an esp32-s2 based product and there are a number of boards that I have built up and am testing, but now two of them are crashing on spi_bus_initialize(). Board number 3 had this problem and I set it aside when I found that other boards weren't crashing at this point, thinking it was s...
