Test DFU with Buttonless DFU

[Aymen Haddar]

I merge all hex file of Bootloader, Bootloader Settings, SoftDevice and Application with Buttonless DFU code included into one hex file. After that, i recover the device. Every thing is good but  when i power-cycle the BMD-350-EVAL, LED1 doesn't blink at all. I don't know why?? 

I hope a feedback soon

Hi,

After that, i recover the device.

Sorry, but not sure what you mean by "recover" in this context. Could you describe how you do it? Also, does the application start BLE advertising after you've recovered?

Thanks and best regards,

Hi Vidar,

It doesn't give me the new ram in the requirements in the debug terminal, it show me the same error in the level of "services_init()":

[<error> app: ERROR 4 [NRF_ERROR_NO_MEM] at C:\rigado\nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\ble_app_uart\main.c:336

You said it went back to ble_stack_init() which is why I thought it was the RAM settings. Can you post a snippet of the code you have around line 336 in main.c? And to confirm again, NRF_SDH_BLE_VS_UUID_COUNT is still defined as '2' in your sdk_config header?

Hello Vidar,

When i Change NRF_SDH_BLE_VS_UUID_COUNT to '2', it went back to ble_stack_init(). Check out the photo, it is about the code at line 336 in main.c.

Hello Aymen,

NRF_SDH_BLE_VS_UUID_COUNT must be set to '2' for this to work. And you will probably have to increase the RAM base after that. See debug log for new RAM settings. 

I only see one screenshot that shows main.c, but that one starts at line ~750.

Hi Vidar,

I changed NRF_SDH_BLE_VS_UUID_COUNT to 2 and RAM_START=0x20002a88

RAM_SIZE=0xd558 and it give me those warnings and errors:

<warning> nrf_sdh_ble: Insufficient RAM allocated for the SoftDevice.
<warning> nrf_sdh_ble: Change the RAM start location from 0x20002A88 to 0x20002AA8.
<warning> nrf_sdh_ble: Maximum RAM size for application is 0xD558.
<error> nrf_sdh_ble: sd_ble_enable() returned NRF_ERROR_NO_MEM.

Hi Aymen,

You need to change RAM START and SIZE as stated in the log. That is, RAM_START=0x20002AA8 and RAM_SIZE=0xD558

Hello Vidar,

I did. Check out the photo

Hello Aymen,

It should be RAM_START=0x20002aa8

[Aymen Haddar]

Hello Vidar,

I change it and when i build it give me 6 error . Check out the photo

Hello Aymen,

Is RAM_START+RAM_SIZE==RAM_PH_SIZE?
