Error when bootloader with Master Control Panel

[trananh]

Hi,

I 'm using MCP v3.9.0.6, softdevice v7.2.0 and pca10003 board.

After load bootloader program to board. I use MCP to load application for it. In MCP, I choose device dfu_targ, connect, discovery services, and DFU choose my .HEX file. But after upload firmware 100%. MCP shows error and I can not solve this

Thanks and regard

Hi Trananh,

Could you let me know the SDK you used ? The MCP v3.9.0.6 may not be compatible with the bootloader in the older SDK. You can have a look at this blog post.

If you are using SDK v7 or v8, and still have the issue, could you provide the MCP log, (click File -> Log) as well as a sniffer trace ?

Hi Hung Bui,

I use SDK 6.1 and I have already read your blog post but when I install MCP 3.7.0, it didn't recognize dongle. How can I solve it?

@Trananh: It seems that I also got the same issue with MCP 3.7.0 that the new Jlink driver is not compatible. I guess you can try either:

• Install older version of Jlink here. Maybe you can try with v4.5. (Make sure you uninstal newer version).

• Porting the new bootloader from SDK v7.0 back to SDK v6.1. It shouldn't be too difficult since they use the same softdevice.

Note that new nordic development kit is recommended (with revision 3 chip) because when you go into production, you will most likely have to use revision 3 chip. And with the new DK kit you can use the latest SDK v9.0

Hi Hung Bui,

Now I only have PCA10003 board.

By the way, what do you mean about "Porting the new bootloader from SDK v7.0 back to SDK v6.1", port example code ?

I tried with Jlink 4.52a but it still not work. Do I need reinstall all of things : nrfTool, nrfgo Studio ?
