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,

i follow this example "https://rigado.zendesk.com/hc/en-us/articles/360025376053-Add-Nordic-DFU-to-a-SDK-Example" and and when i reach to test the test the DFU buttonless with the new application. This latter doesn't start adversting and the LED1 doesn't blink.

Hello Vidar,

Yes i confirm there is a app error handler.It doesn't enter "ble_stack_int" function which include "Register a handler for BLE events" and new window open called "app_error_weak.c".

Hello Aymen,

The code above the breakpoint condition will not be greyed if you select the 'Debug' target from the drop-down menu in the top left corner and do a re-build. Do you see log messages in the SES console when you debug the app? 

[Aymen Haddar]

Hello Vidar,

No can't see the log message in the SES console but it running at  "NRF_BREAKPOINT_COND;" and it show me app_error_fault_handler(....).

Try to set NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED option in sdk_config.h to "0" and recompile the app again. That should fix the problem where the debug messages are not shown in the SES Debug terminal window.

Hello Vidar,

I change NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED option in sdk_config.h to "0" and recompile the app but when i start debugging step by step, it gave me an warning "Insufficient RAM start location for the softdevice" and error "sd_ble_enable() returned NRF_ERROR_NO_MEM".

However, in the tutoriel i change the RAM_START by increasing it 0x10  and the RAM_SIZE decreasing it by 0x10 with new value as following :
RAM_START=0x20002a88
RAM_SIZE=0x3d558

can you give me a solution for this issue??

Hello Aymen,

It may be a typo in the tutorial or a different configuration. Either way, the minimum RAM start address is 0x20002a98 according to the crash log. So you need to change it in your project settings.

Hi Vidar,

I changed the old value:RAM_START=0x20002a98, RAM_SIZE=0xd568 but It still stuck at  "services_init();"  and go buck to  "NRF_BREAKPOINT_COND;".

So you're getting past ble_stack_init() now, that is good. But don't you get a new crashlog now when the program reaches the breakpoint (NRF_BREAKPOINT_COND)?

Hello Vidar,

yes, when i debug the app with Debug configuration, it give me an error like this at the Debug Terminal

"<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
PC at: 0x0002E925"

Hello Aymen,

Not sure if it was mentioned in the blog post, but NRF_SDH_BLE_VS_UUID_COUNT in sdk_config.h must be bumped to '2' since you're adding the DFU service. Have you done that?
