DA14681- Wearable. 2nd stage bootloader rejected
Posted byMer1061120 points 5 repliesHi,
I recently received a DA14681 Wearable kit, and am trying to use Smart Snippets Studio to reprogram it. I have imported the sample project into the studio. When I attempt to flash it to the device using program_qspi_serial_win I receive the following error:
写出可执行失败:bootloa第二阶段der rejected (-105)
I am also unable to connect to the device via J-Link Commander, with the following error:
Could not measure total IR len. TDO is constant high.
The SDK version that I am using is 1.150.6 (according to//www.xmece.com/products/da14681-wearable-developm…).

Thanks for the reply.
The kit came with an external Communication Interface Board which claims to have a SEGGER chip running JLink-OB firmware. I assumed this was all that was needed to program the wearable kit - do I still need a Pro-DK? Apologies if I have misunderstood.
Thanks

Hi Mer10611,
Apologies - probably I misunderstood it. Since you have the Communication Interface Board (CIB) , you don't need the Pro-DK, as it has a SEGGER chip as you mentioned correctly.
Please make sure that you have the correct configuration - see section 4.1.1 :
Can I ask what is the version of SmartSnippets Studio(SSS) that you are using? For DA1468x product family, we recommend using SSS v1.6.3. You will find it in "Development Tools" section :

Additionally, we have asked someone to reach out to you directly.

Thank you! I downgraded my version of Smart Studio from 2.0.7 to 1.6.3 and now it's all working.
EDIT: Downgrading Smart Studio worked the first time, however I am trying to upload a new build and am receiving the same errors as I was previously with the new SS.

Hi Mer10611,
Glad that is working. You can also use the SmartSnippets Studio v2.0.16. It can be found it in "Development Tools" section too:

Hi Mer10611,
Thanks for your question. The Wearable Kit does include a JTAG interface, so you will need to use an external SWD interface to program it.
Please check section 4 in the following document :
//www.xmece.com/sites/default/files/um-b-077_da14681_wearable_development_kit_hardware_manual_1v2.pdf
Do you have a Pro-DK? I assume that you can try to program the Wearable Kit via the Pro-DK.

We strongly recommend DA14682/683 for new designs.
Thanks, PM_Dialog
