Program custom board nrf52811 with PCA10040

[StephaneJ]

Hi,

I have a custom board running with the nrf52832. To program it I'm using the nrf52DK board with the PCA10040 and the bootloader is based on the one found in examples/dfu/secure_bootloader/pca10040_ble so using the softdevice s132

Due to the lack of inventory everywhere with the nrf52832, we are testing a version with a nrf52811.

My questions are :

- Can I use the same hardware (nrf52DK PCA10040) to program my custom board with nrf52811 ?

- How can I use the bootloader with the softdevice S140 because it is only available inside the pca10056_ble folder

Thanks

Hi,

It should not be any problem to use the  nrf52DK PCA10040 for programming of the 52811 IC, but you will obviously need some FW  that's correctly configured for this chip variant (correct startup files and linker configuration). Are you sure you will be needing the s140 Softdevice, and not the smaller s112 or s113 variant? There won't be much room left for the application if you use the s140 as you can see from the standard memory layouts here "Memory layout"

Best regards,
