Re: DPORT access workaround and high interrupts.

Hi Malishev, Thanks for reporting this and being patient while someone got back to you. You're correct that using a high level interrupt will currently break the DPORT access workaround. The fix seems like it should be as simple as having the workaround disable higher priority interrupts as well. We...

Re: What manufacturing defect can cause lack of WiFi functionality?

Hi Panican, Is it possible you have a cold joint under the ESP32 QFN pad for the antenna? Is your crystal 40MHz and its frequency tolerance is good? May be worth comparing XTAL frequency on working vs non-working boards if you can. Does reworking the antenna components fix the problem on any of the ...

Re: Corrupt MAC address in efuse

Hi, Sorry we never responded to markwj's original post for some reason. themadsens, I have a couple of questions: - Does this only happen when waking from deep sleep? If you cycle the power does the ESP32 start correctly from power on reset? - How is the ESP32 being powered in deep sleep? What volta...

Re: esptool write_flash with encrypt option

Unless there has been some change to the ESP32, I would assume that we should be able to accommodate whatever changes are needed for the new workflow. Yes, that's correct. The other work is all in the ESP-IDF documentation, configuration and build system. Thanks for being patient while we finalise ...

Re: vTaskDelete sometimes hangs current task

Hi maldus, I'm glad you got everything working smoothly. (the situation you described should not be possible, as only one task can be reading or writing the list of processes at any given time). I saw the semaphore protecting the process list and it looked like it would mostly protect in this way, b...

Re: vTaskDelete sometimes hangs current task

BTW The usual way to structure the kind of "worker tasks" arrangement you're building is not to create/delete tasks at all, but to have a worker pool who can either be idle (blocked receiving from a command queue) or currently working on a command. There's no reason what you're doing can't work, but...

Re: vTaskDelete sometimes hangs current task

Sorry, this is still not anything close to the kind of minimal example that we could use to reproduce the problem and show if it's likely to be an ESP-IDF bug. The only way I can debug with this example would be to debug your application logic, tasks framework, etc. We don't have the resources to de...

The corrupted looking output was after I flashed the partition table. Which ended up partially writing over the bootloader so that might have been where that issue came from.
Of course, that makes sense. Glad you got everything working.

Re: esptool write_flash with encrypt option

1. It's not clear to me how to take advantage of the "less secure" options. Is there documentation on how I would use those to go beyond the 4 flash limit? What would the process look like? Unless you really want to dig into the semi-documented details, it's probably easiest to wait for the new "de...

Re: Updating to stay as close as possible to release/v3.3

Hi jcsbanks, In additional to what Sprite says, note that after the v3.3 final release we will continue to backport bug fixes to this branch and then later tag v3.3.1, v3.3.2, etc after we finish QA testing based on a particular commit from the branch. So you may want to keep an eye out for the v3.3...
