SDK 12 Bootloader DFU PROBLEM

[carloscoelho]

Hi, 

I intend to use the DFU BOOTLOADER in my product.

I’m using a PCA10040 DEV board for the tests with S132

I download the nRF SDK V17 and I compiled and  I tested the “secure_bootloader” program  with  the “ble_app_buttonless_dfu” program, I did create the private keys and 

it works fine.

My product application was written with SDK 12, so I’m trying to do the same test with SDK 12.

I downloaded the nRF SDK V12 and I did the same procedure with my PCA10040 DEV board and S132(3.0.0) SoftDevice.

I compiled and tested “secure_bootloader\pca10040_s132_ble” program  with S132 SOFTDEVICE (3.0.0) .  The bootstrap runs, the BFU icons apears on the nRF APP but when I try to connect to the PCA10040 board the program  hangs and disconnect.

If  I use the HEX file with the “secure_bootloader\pca10040_s132_ble”  program that came with the SDK, it works fine, I’m able to do the whole process.

I’m using GNU Tools Arm Embedded\9 2019-q4-major to compile the SDK.

Thanks in advance,

Carlos

Hi Carlos,

The GNU Tools Arm Embedded version used for release testing SDK 12.x was GCC ARM Embedded 4.9 2015q3, so I recommend you use that. If you still see problems, can you test with the debug bootloader project with RTT logging? The log may give some useful indication of what happens.
