Laird BL653 (nRF52833 based) Development - "make flash" failure

[jcvandegrift]

Environment:

• Host: Macbook Catalina
• SDK: 16.0.0
• Toolchain: ...2018-q2... (the pre-configured toolchain in the SDK)
• SoftDevice: (not used yet, planning to use 6.0.0.6-alpha)
• Nordic example: examples/peripheral/saadc/pca10100/blank/armgcc
• Target: Laird BL653 (documented as same as PCA10100 except for Button 4 Pin Assign and Clock Configuration), I modified the PCA10100 config to match the Laird DevKit
• JLink: USB port to Laird's Segger HW

(base) MacBook-Air:armgcc jvandegrift$ make # ... this "just worked" so I'm not showing the clean output

 

(base) MacBook-Air:armgcc jvandegrift$ make flash

ERROR: The --family option given with the command (or the default from

How I could have the "family" wrong if the Laird is built on an nrf52833 SoC and "-f nrf52" is provided as an arg?

Thanks,

Jeff

My thinking is that I can do the following:

• Figure how the BL653's self description during nfrjprog / JTAG negotiation differs from PCA10100
• Clone PCA10100 info (how many places?) and name the copy BL653
• Modify the parts of the new BL653 Config such that nfrjprog will recognize the BL653 HW as "within the nrf52 family" and write the program

Am I on the right track? It'd be helpful to identify the places to be modified.
