The API guide for external RAM mentions that extram_bss "linker fragment scheme" can be used to force all bss of a component into external RAM. Can someone show the code syntax to use this technique? I am on 4.0 and 4.4 IDFs using cmake. Here is an example CMakeLists.txt for one of my application co...

It seems that the IDF system components in 4.4 take up a lot more internal RAM than 4.0. I am using ESP32-WROVER-E (ECO v3) and I saw that v3 silicon should allow free use of the external PSRAM for task stacks. https://esp32.com/viewtopic.php?t=21520 However, I get crashes if my task accesses flash ...

My solution, which I found myself, was to re-install IDF 4.0 from scratch but before installing tools, hack the tools.json file. It will download the desired openocd version and install it as it installs all the other tools. This went smoothly and works well with Eclipse 2021-06 for JTAG debugging. ...

I have just started using JTAG in Eclipse with the hope to diagnose an interrupt WDT that just started occurring after some recent changes to stable code. I want to let my system run in Debug mode until the problem occurs and I can see where the problem came from when it breaks due to WDT. Although ...

I am just starting to work with JTAG debugging. I am trying to demonstrate basic operation with command line. I now successfully get openocd and gdb running. I can reset and break at app_main, then step through lines of code. However, I see a warning in the openocd window: Info : Set GDB target to '...

I am trying to get JTAG debugging working for gdb from Ubuntu command line per instructions on espressif website. I have IDF 4.0 release and openocd 20190313. I wish to update openocd to a newer version, without changing any other parts of my toolchain. I am not sure which scripts need to be manuall...

TensorFlow Lite for Microcontrollers is part of the normal native TensorFlow repository. But Espressif has its own fork as well. I usually assume an ESP-specific version of a component has simplification or improvements for esp32, as compared to the creator's generic repo version. I am trying to det...

I restated the issue in a new forum post, including how to reproduce using IDF example code.

Hello, I posted about this a month ago and received zero responses. This continues to be an issue in the latest release/4.1 code. If not fixed, I will not be able to leave IDF 4.0 and move to 4.1 or 4.2. Previous post with large amount of detail: https://www.esp32.com/viewtopic.php?f=13&t=16023 (1) ...
