Hi nick,

CMake is no longer a preview and this is supported on ESP-IDF v4.x.

However, I'm able to reproduce this problem. The verification key binary is being linked to the bootloader correctly but not the app. Will fix ASAP.

Hi JadElClemens, Thanks for the detailed description of what you're seeing. I have some additional questions to help figure out what's happening here: Which ESP-IDF version do you have? Do you have Wi-Fi or BT enabled at the same time? When you say you raised the priority "above all other tasks", ho...

Hi schnaaabeltier,

What ESP-IDF version do you have? This was a bug in v4.0-beta1, but it's been fixed and you can get the fix by checking out the latest release/v4.0 branch. There will be a v4.0-beta2 prerelease soon.

Hi zliudr, Unfortunately the newlib we provide with ESP-IDF was compiled without regular expression support. The header is still there as it's part of newlib, but the symbols aren't actually available to link against. We may be able to fix this in the future, if you have a GitHub account then you ca...

Hi Mokatronics, Your English is absolutely great, no need to apologise. Thanks for all the detail. The output from your "Arduino Nano" trace of the serial exchange shows that esptool is not able to reset the board properly into bootloader mode - it's booting into "normal" mode which has the incomple...

Hi dani619, There's no officially supported C tool for flashing an ESP32. There have been some community projects but I'm unsure of their status, you can search the forum to find some discussion about them. If you only need a way to run esptool without a separate Python environment installation, the...

Hi wevets, Thanks very much for letting us know about this problem. Do you have a link to a page where this happening? I tried the Sleep Modes page for the function mentioned in the post, but it's rendering OK for latest master branch and the v3.3 stable release: https://docs.espressif.com/projects/...

How I see, fat still is not working on encrypted partition.

This should work now. If it's not working, can you please give some more details (ESP-IDF version, exact configuration & setup, behaviour you're seeing when trying to use the FAT partition.)

Hi jsam589, WiFive is right. ESP-IDF doesn't support OTA updating of the partition table because a power failure or crash during the update could brick the device. If you're confident this won't happen then you can disable the config flag that the prevents SPI flash APIs from erasing or writing "sen...

Hi glarty, This is a hardware limitation. You can't concurrently map more than 4MB of PSRAM memory into the address space of an ESP32 (this limit is raised in the forthcoming ESP32-S2 Beta). Working around this limitation is why the Himem API that you mentioned was created: https://docs.espressif.co...
