Cannot run ble_app_blinky_pca10040_s132 example on Fanstel BT832

[gschelotto]

Hi,

I'm trying to run ble_app_blinky_pca10040_s132 on Fanstel BT832 custom board with no success. After writing/verifying the app using the SES it jumps to 'unknow function 0x00000A60' instead the main() entry point.

The optional 32.768KHz Xtal is not populated on my board so I changed the sdk_config.h as suggested in this post. This still does not work.

I'm using the latest s132 softdevice (s132_nrf52_7.3.0_softdevice)

Any hint from DevZone support?

thanks in advance,
gaston

Hi,

Which SDK version and project folder are you using? Have you made a custom board file for your board?

After writing/verifying the app using the SES it jumps to 'unknow function 0x00000A60' instead the main() entry point.

It doesn't even reach the start of main()? Have you made sure that the softdevice is actually flashed?

regards

no. I'm running the example as is it

No, it's stuck at 0x00000A60

I'm using nrfconnect v3.8.0 (Programmer Tool). Here's my memory layout after writing softdevice and application hex

Seems like nRF Connect Programmer recognize it as nRF52810 not nRF52832. If it's indeed the former then the PCA10040e is the correct one. Can you use nrfjprog and read out the INFO.PART register?

Hi Jared,

Thank you for your help.

What's the difference between PCA10040 and PCA10040e?

How can I read out the INFO.PART register with nrfprog utility?

PCA10040e is made to emulate the nRF52810 on the nRF52832 PCA10040 development board. The nRF52810 does not have its own development kit, the choice is therefore to use the PCA10040e folders if you develop for that IC. You can use the memrd command, the register is at address 0x10000100:

nrfjprog --memrd 0x10000100

Hi Jared,

The module I use is a BT832A not BT832 as I had said. Therefore it uses the nRF52810 SoC. I've used the memrd command to confirm this and programmed the device with the PCA10040e hrs example.

Everything goes well and it works as expected.

Thank you very much for your help!
