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?

Hello Aymen,

Is RAM_START+RAM_SIZE==RAM_PH_SIZE?

[Aymen Haddar]

Hello Vidar,

No, it give me this result 20002aa88 + d558 = 200037FE0 and the RAM_PH_SIZE = 80000

Hello Aymen,

I guess it would have been more accurate to ask if RAM_START+RAM_SIZE == RAM_PH_START +RAM_PH_SIZE. Anyway, the problem is that you haven't typed in RAM_START correctly.

Hello Vidar,

I try it with old value and the new value of RAM_START and RAM_SIZE, it doesn't work. The value as follow:

***new value

RAM_START=0x20002a88
RAM_SIZE=0x3d558

***old value

RAM_START=0x20002a98
RAM_SIZE=0xd568

Hello Aymen,

Where are you getting the values from? The debug log you sent me earlier is instructing you to set RAM start to 0x20002AA8 and size to 0xD558. 

<warning> nrf_sdh_ble: Insufficient RAM allocated for the SoftDevice.

Hello Aymen,

I'm asking you to change it to 0x20002AA8, not 0x20002AA88 which is way above the valid memory range.

Thanks a lot Vidar.
