DFU not working on S332 2.0 SDK12 . Help me setting Target IROM1 and IRAM1?

[Wasil]

Hi 

   I am trying to implement DFU to my project. I have done all the steps to generate packages,  private and public keys etc. My program now starts at dfu and I can upload the package to nrf52 but it then get stuck to (Jump to 0x0029000).

Can anyone help me target setting on keil? Thanks

Hi Stark,

Could you try to test updating an example in our SDK (you need to configure it so it works with S332) instead of your application, just to make sure that DFU works properly ?  You can also start with testing with a simple application to blink an LED. 

I assume your app works if you don't flash the bootloader ?

Hi Hung,

             I got successful in running dfu on s132 but struggling on s332. I think its IROM1 and IRAM1 settings for dfu bootloader. Currently settings are

IROM1: 0x75000 and size: 0xB000

IRAM1: 0x20002E00 and size: 0xD370 

I am working on nrf52832 512k chip. 

Is there any way to find out the correct IRAM1?

I have just checked your package file and bootloader. It uploads package OTA but then I see it stuck. LED stays on all the time also cannot find on nrf connect app :-(

((I don't see any softdevice enable before sd_power_dcdc_mode_set(). You can't call softdevice API before you enable the softdevice)..... how to enable it? I thought preprocessor directives enabling it. )

I know what you mean now. 

it stuck in SOFTDEVICE_HANDLER_INIT(&clock_lf_cfg, NULL); routine. I have check the XTAL settings and it looks fine to me.

One thing I do not understand that App works fine without bootloader. Bluetooth and ANT+ both works ok. 

Bootloader change some thing? or memory over flow(which i doubt) or anything else?

One more thing I would like to add is when I install app OTA and disconnect from DFUTarg it restart from dfu boatloader again? This even happened with the example files you sent.

Hi Hung,

sd_softdevice_enable(p_clock_lf_cfg, softdevice_fault_handler, ANT_LICENSE_KEY); Thats exactly where it jams. Need your help. Thanks

I think we need to focus on why the hrs example I provided didn't work for you. It worked fine here.

Do you nRF52 DK for testing or it's your own hardware ? 

Do you have any trouble testing the ble_app_hrs for S332 in our SDK (without bootloader)

If you test using the blinky .zip package do you see the problem that you mentioned "when I install app OTA and disconnect from DFUTarg it restart from dfu boatloader again?"

The only potential issue I can think of is if the bootloader using something (for example Timer, UART) and then in your application you use the peripheral without reconfigure it properly. Then you can get into trouble. But it should not be the case with the ble_app_hrs image that I sent you.

Q1) I am testing on my own hardware. 

Q2) I have tried ble_app_hrs for s332 without bootloader and it does the same like with dfu bootloader(i.e. LED stays on all the time)

Q3) I have checked again and it jumps to blinky app.

How to reconfigure peripherals?

Also I tried dfu on s132 and it uploads and run my app without any issue. Its just s332v2.0 causing issue.

Could you read the laser marking on top of your nRF52 chip ? 

Do you have the 32kHz crystal on your board ? 

[Wasil]

I am using nrf52832 module from Raytac and according to their technical specification its 32KHz crystal. Module tech spec attached. Thanks MDBT42Q-Version B (1).pdf

If I send you my project package file can you check if that runs on your machine?
