Flash ERROR with the j-link debugger

[Jack han]

Hello I currently have an error when flashing with j-link on a custom board.
The mcu is nRF52833 QDAA and the debugger pin is connected to 4 pins.
In VSCODE, CONNECTD DEVICES in CONNECTD DEVICES, the MCU name comes out at first, but then it doesn't come out immediately. I'm attaching a picture of it. Is there any solution?

Hi

This is something that is lacking in the board creation option in VS code unfortunately. When making the board, you can create the board on top of QIAA and change the following references to make them match QDAA:

• Kconfig.board: replace SOC_NRF52833_QIAA with SOC_NRF52833_QDAA
• myboard_defconfig: replace CONFIG_SOC_NRF52833_QIAA=y with CONFIG_SOC_NRF52833_QDAA=y

• myboard.dts: replace #include <nordic/nrf52833_qiaa.dtsi> with #include <nordic/nrf52833_qdaa.dtsi>

Best regards,

Simon

Will this change the number of pins in the pin map to match the QADD?

[Simonr]

Yes, this should make the board file match the QDAA SOC, as the Kconfigs and .dts files already exists, but the board creation in VS code doesn't have these yet.

Best regards,

Simon

I changed to QDAA, but when I look at the pin configuration, it only shows up to pin 31. I saw in the datasheet that QDAA PINs can be up to 40. How can I make pin 31 show up to pin 40?

Hi, there are 40 pins there, but there are only 32 pins per port, so the last 8 pins are on P1. Please refer to the pin assignments in the PS though, as all these pins aren't available on the physical chip. There are also pins for VDD, VSS, DEC, etc.

Best regards,

Simon
