Numerous errors in build process of Adafruit nRF52 Bootloader on Segger Studio

[Sir Oswald Mosley]

Hello , I am trying to build the bootloader source code provided by Adafruit for its nRF52 core. The project is based in Segger Embedded Studio. 

Adafruit's nRF52 core bootloader is based on the non-secure bootloader in nRF SDK version 11.0.0_89a8197.

During the build process, I am facing numerous errors. After looking into similar posts on this forum , I have deduced that the errors could be due to configuration set in the sdk_config.h. 

To reproduce the issue, the following repository must be cloned : https://github.com/RAKWireless/WisBlock 

Then browse to Segger project path , and open the Segger project for the bootloader source code.

While building the code, I see the following errors : 

There a total of 253 errors in the usb.c

The following errors occur in usb_desc.c and ghostfat.c : 

Hardware that I am using is a nRF52480 based SoC.

Hello Sir Oswald, 

I'm afraid that we have very little experience with the Adafruit bootloader. I would suggest you to send the question to Adafruit or RAK wireless to get support from them. 

[Sir Oswald Mosley]

Adafruit support team is non-responsive and RAK support does not seem to be much aware of the low level working of the bootloader. Therefore, I was hoping to get some solution from here. The errors here are related to the NRF SDK (v11).

I was looking at the error but as far as I know we don't have USB supported in the bootloader in SDK v11 so I don't know what the error is about.
