Use ST-Link as ICE debuger for the Spresense

[leo 1]

Do you know if it's possible to use ST-Link as debuger for the Spresense?

I first check the recommended debuggers in the documentation but there is only two reference. One of this reference Keil ULINK2 (http://www.keil.com/arm/ulink2/) is really expensive (more than 400 $) and the other NXP LPC-Link2 (https://www.nxp.com/jp/support/developer-resources/software-development-tools/lpc-developer-resources-/lpc-microcontroller-utilities/lpc-link2:OM13054?lang=jp&lang_cd=jp&) is no longer available.

@leo-1
I was successfully using the successor of the LPC-Link2. It is https://www.nxp.com/design/microcontrollers-developer-resources/mcu-link-debug-probe:MCU-LINK. This is very cheap.

One hint about an issue I ran into. The latest version of the Cortex-Debug Plugin of Visual Studio does not support anymore the quite outdated GDB version of the Spresense SDK.
Try downgrading to version v1.4.4 if you get errors.

@CamilaSouza Did you get feedback about gdb already? It might make sense to update instructions if you can verify the issue.

Regarding the ST-Link. You need a cmsis-dap compatible device. Please check for this. (A quick google search let's me think it is not. But please counter check. I only spend 3 minutes on this search)

I also tried a nRF52840-DK. It was not compatible.

Do you mean to ask if I received feedback from other users?
I haven't, sorry.

I'll raise this issue with outdated GDB version so we can verify.

Thanks for tagging me.
