Re: ESP32-D2WD Based Custom board JTAG Flash issue.
Other Forums have reported errors trying to run JTAG with the WROOM that are fixed by getting the more current version. Unless someone has made a tool change, it is a pain since after removing the installed version and installing the more current release from https://github.com/espressif/openocd-esp...

Re: ESP32-D2WD Based Custom board JTAG Flash issue.
Your openOCD is bit behind, you seem to be using November 2019 C:\Users\eralp\.espressif\tools\openocd-esp32\v0.10.0-esp32-20191114\openocd-esp32\share\openocd and I was not successful until I upgraded to July 2020 C:\Users\sbonomi\.espressif\tools\openocd-esp32\v0.10.0-esp32-20200709\openocd-esp32\...

Re: ESP32-D2WD Based Custom board JTAG Flash issue.
I had issues understanding the basic openocd output also.
I will suggest that you use "-d3" to turn on more debugging log entries.
For my system I also add " -l ./MyLogFileName.log" to the command line so I get the output in a form I can loot at it later.

Re: RTC Clarification Requested
Sounds like a perfect example of a future improvement. Having something close to correct time when coming up can be very useful. It will not be good enough to reuse a timeslot in a 5G network, but it does help in MeanTimetoFirstFix for a GPS type system if it has some idea of which satellites are re...

Re: JTAG Optimized to unusable
Yes, in this function, len is a const during each iteration of the function, but different for each instance of the function. It is not JUST len that is optimized out. All the incoming arguments are optimized out, as well as most, if not all, of the local variables which are put into registers. The ...

Re: Feed an ESP32 project
There is some control on the amount of power available to each GPIO. You may be running into control problems with too great a parasitic power draw from too many components. Watching the I2C IO with a scope could be valuable. You might also want to look at distance to the motors. The length and size...

RTC Clarification Requested
RTCs I have used in the past usually had a cap and a diode to keep them powered for a while. But the memory in them was persistent so even a long power outage would result in a system time that is later than the last reported event, even if not completely accurate. What I am seeing at this time is t...

Re: esp32-pico-d4 flash error
I had a similar issue on my custom board, to activate the serial load feature GPIO0 has to be low at reset. The dev kits do that with a couple of transistors and using the DSR line from the USB. I have to take a probe,, and ground a pad on the board before hitting the system reset switch. Next spin ...

Re: JTAG Optimized to unusable
I see that no answer is forthcoming
changing to
OPTIMIZATION_FLAGS = -O0
in esp-idf/make/project.mk
had no effect on the optimizations either.

JTAG Optimized to unusable
How do I limit/Prohibit the optimization in the IDF successfully . According to the GCC on line manual, __attribute__((optimize("O0"))) should stop all optimization in that module, When I get there with GDB and JTAG, The names are gone. I do not see a strip statement in the build. It would be nice t...
