Segger J-Link with openocd (XMC Link) fails during connection

I'm using ESP32-D2WD on a custom board and have disabled the SPI code/GPIO setup/etc on the JTAG pins (GPIOs 12-15). After switching XMC Link to libusb driver, I am able to get this far from msys2 console: $ bin/openocd.exe -s share/openocd/scripts -f interface/jlink.cfg -f target/esp32.cfg Open On-...

Re: Read Issue with UART 2

I was able to solve this by changing rx_flow_ctrl_thresh from 122 to 40.

Re: Issues flashing D2WD/flash status meaning?

This update is working well. However, it seems to require reflash of the bootloader. Any suggestions for OTA? Should I just re-write the bootloader in the field (seems risky)?

Re: Issues flashing D2WD/flash status meaning?

I'm suspecting the VSDIO line, as all of these issues started when we moved to 1.8V from 3.3V. Can you elaborate on what this means? Unfortunately, if you had MTDI strapped to 3.3V for an extended period, the flash itself may be damaged. I have older devices that ran at 3.3V that starting having is...

Re: Issues flashing D2WD/flash status meaning?

Or should I consider raising the flash voltage to 3.3V for erase/flashing operations? I am noticing some dirty erase cycles where I have to do a blank check and re-erase once or twice to actually get a 0xF0000 block cleared.

Re: Issues flashing D2WD/flash status meaning?

I'm suspecting the VSDIO line, as all of these issues started when we moved to 1.8V from 3.3V. We have close to 100uF on the 3.3V main rail, and the regulator is LT3973EDD-3.3. The VSDIO is using internal LDO and only has the recommended 1uF capacitor attached (very close to the pin) with no other t...

Re: Flash erase/write/read test failing

Also - is there a way I can disable caching of read/write operations to flash or do the partition read/write functions bypass caching?
