Re: Guru Meditation Error: Core 0 panic'ed (LoadStoreError) : a problem of ROM?

Without more details it's impossible to know what the problem is. Can you please post more context, or the full output when it crashes? If the output contains raw addresses then you can use tools like idf_monitor to decode them to line numbers: http://esp-idf.readthedocs.io/en/latest/get-started/idf...

Re: 26MHz TCXO (not crystal) -- which pin to connect to?

One additional question though: With the ECS-TXO-2520 we have 2.5 ppm from -40C to 80C. Will the RTC and internal oscillators be calibrated against that very stable reference as temperature drifts? Are the PLLs locked to the external oscillator? Or in short: does using a TCXO imply I don't have to ...

Re: How to check if an efuse has been burnt?

We don't have a generic API for this in ESP-IDF, although there are some for particular functions (like secure boot & flash encryption), but they tend to be at the "is this feature enabled?" level rather than anything about the efuses. "espefuse.py summary" will give you this...

Re: make menuconfig fails with file not recognized: File format not recognized

Hi raspberrypisig,

Thanks for the detailed description of the problem.

If you run

Code: Select all

rm $IDF_PATH/tools/kconfig/*.o
and then re-run make menuconfig, what is the output?

Re: OTA-Update strategy (regarding IDF updates, bootloader etc.)

Sorry this post somehow got skipped over for so long. Should we work with a constant IDF or may we update IDF when compiling the OTA update APP. Could there be breaking changes in the app with respect to a then potentially outdated bootloader (which cannot be updated via OTA), e.g. some peripherals ...

Re: What does "Image contains multiple DROM segments. Only the last one will be mapped." mean?

Hi Gfast2, It looks like some of the source files in your library are being compiled to unexpected section names, and these section names are being linked into the ELF file and then the binary in a way which the ESP-IDF bootloader isn't designed to handle. This is probably in the open62541 library t...

Re: ESP32-PICO-D4 Reference Board Schematic

Is there a reference schematic that notes recommended layout, supporting hardware, and so on? There is a schematic on Section 6 of the datasheet: http://espressif.com/sites/default/files/documentation/esp32-pico-d4_datasheet_en.pdf (The antenna matching components are marked TBD because their selec...

Re: Suggestions for finding stack/program counter corruption

I am wondering if there are any other options/tools to get information when the exception handler is called because both the PC and A0 registers contain nonsensical values when this occurs. JTAG (which I saw you've ruled out) is probably the best option, although even at the point it breaks into th...

Re: How to understand some macro only found in esp-idf's components folder?

If I didn't found its definition there, is that means, it is not supported by esp-idf? But why there is still some thing call this macro? That's correct, it's not supported. The references to it are in the nghttp2 submodule, which is the full upstream source of nghttp2 - we clone it unmodified so i...
