Re: ESP32 nvs_get_blob() help

I ran your code, and it prints the following: get_configuration_values() ssid:ESP32 err:0x1102 reqsize:0 get_configuration_values() pass:password err:0x1102 reqsize:0 Note that the error is 0x1102 (not 0x102), which is ESP_ERR_NVS_NOT_FOUND. Looking at the code, it makes sense, because 'nvs_set_blob...

Re: Allocated memory in RTC

It is not possible to do dynamic allocation in RTC memory, but you can do static (compile-time) allocation. If you define a global variable with RTC_DATA_ATTR attribute, the variable will be placed into RTC_SLOW_MEM memory. You can see how this is done in sntp example: https://github.com/espressif/e...

Re: Writing to flash encrypted NVS storage during manufacturing

At the moment, nvs doesn't support encrypted partitions. That's something we will be working on for the next version.

The easiest way to generate nvs data is to initialize the contents of nvs on one board, and dump the partition using esptool's read_flash command.

Re: Unstable partition API flashing functions

Thanks for the stack dump, this confirms what we thought is the cause of this. Could you please try adding this line into components/esp32/ld/esp32.common.ld, near line 88 (next to *libesp32.a:core_dump.o ): *libesp32.a:heap_alloc_caps.o(.literal .text .literal.* .text.*)

Re: its too slow to get IDF from github, is there any other solutions ?

We will start by providing a downloadable copy for the 2.0 release next week.
Based on the feedback, we will add downloadable releases for the master branch. Expect to see this in a couple of weeks.
