Hello,
Sorry for late reply, I have updated the repository now and now it compiles and I also merged the latest black magic code.
As well as support for the esp32-c3 over JTAG. This has not been tested however.

The cache_flash_mmu_set function is documented in the cache.h header file. Because of ... reasons, the rom function cache_flash_mmu_set_rom almost does the trick, but also allow the other core to run around and possibly fetch instructions from the flash when no flash is mappped. That could cause pro...

However, Examples are still in Chinese only.
With help of google translate I put a translated versions as well as a "blink" example here.

I think this might be what you are looking for: https://docs.espressif.com/projects/esp ... 1-kit.html

Yes. Thank you.
Now we are waiting for ULP coprocessor (RISC-V) — support (IDF-521)

Expensive but it is a nice board for doing experiments, with several daugtherboards and a camera. I also like the built in JTAG controller and the extra breakout pins. I translated some examples from Chinese but hope espressif will have official support soon. https://github.com/Ebiroll/esp32s2_kalug...

Yes. After moving the switches It seems to work.

Thank you. I edited the previous post so it should be correct. When I tested I did not get contact. Error: JTAG scan chain interrogation failed: all ones Error: Check JTAG interface, timings, target power, etc. Error: Trying to use configured scan chain anyway...

Hello, I cannot find any JTAG board configuration file for the kaluga-1 dev board. Any chance that this might work? board/esp32-kaluga-1-3.3v.cfg # Example OpenOCD configuration file for ESP32-KALUGA-1-KIT board. # # For example, OpenOCD can be started for ESP32 debugging on # # openocd -f board/esp...

I was able to order a Kaluga board from Digikey. Still 8 in stock. https://www.digikey.com/products/en?keywords=kaluga . I could not find so much documentation online, so I thought I post my findings here. https://github.com/Ebiroll/esp32s2_kaluga. I expect to have some information within 12 hours, ...

Hello again, I found part of the answer. 0x40062a6c is marked as reserved, but is most likely part of the rom and related to the spi_flash functions. https://github.com/pycom/esp-idf-2.0/blob/master/components/esp32/ld/esp32.rom.ld PROVIDE ( spi_flash_attach = 0x40062a6c ); void spi_flash_attach ( u...
