Matthias Jentsch posted a comment on ticket #466
I've tested this with an ESP32-WROVER-E WCH JTAG DevKit which has a CH347 chip with firmware version 5.44 and found that's working. It's the current version that's delivered with ESP-IDF 6.0-beta2. Tested on Ubuntu Linux. Here is the log output: Open On-Chip Debugger v0.12.0-esp32-20251215 (2025-12-15-18:17) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html Warn : DEPRECATED: auto-selecting transport "jtag". Use 'transport select jtag' to suppress this message....

bug with J-Link debug

J-Link sees zero target voltage, that likely means your reference voltage input is not connected to target's Vcc so J-Link can't communicate not knowing what voltage to use.

Tested with RP2040 and latest openocd and fails, Distro openocd works for RP2040,. See video.

No wonder as you're using the latest but too old release (0.12 from January 2023) and RP2350 flash support was merged in April 2025. Don't combine config files downloaded from untrustworthy sources with different OpenOCD binary. Either use fresh upstream git master (build from source or a prebuild pack) - it will support rp2350 except RISC-V cores, or use RPi fork https://github.com/raspberrypi/openocd for complete rp2350 support

Comparing the Samsung K9F1G08U0D (2048 + 64 page size) datasheet with that of K9F1G08U0C (512 + 16 page size), you can realize the significant difference of spare data handling. For the 2048 page size NAND flash, the spare area is selected by the highest column address. For the 512 page size NAND, there's no such a bit in the address sequence, but the spare area can be read by the NAND_CMD_READOOB command. The page program command supports loading 512 + 16 bytes at once, writing the page data with...

I cannot see the connections in the pictures nor the pinout of the DAPLINK, but the removed jumpers are ok. You need to connect the GND between the boards, for sure, and VDD 3.3V as you said required by your DAPLINK. The SWDIO goes to PA13, that is on pin 13 of CN7 The SWCLK goes to PA14, that is on pin 15 of CN7 Probably you have simply swapped SWDIO and SWCLK. Or, the firmware in the STM32F446 is blocking the SWD interface. Without a NRST driven by the DAPLINK, you can try to keep pressed the black...

I have done still same issue :
-
On the Nucleo board there are two jumpers, just above the crystal of the on-board ST-Link. You need to remove them to isolate the SWD port of the ST-Link from the F446. With the jumpers in place, the on-board ST-Link will prevent using the external CMSIS-DAP. Please reply if this fixes the issue, so we can close the ticket
