Memory settings for working with rigDFU (Rigado BMD-300)

[Sébastien Schiesser]

Good evening (at least here...)

I successfully developed an application with Keil on the Rigado EVAL board with the following steps:

1. nRFgo Studio -> erase all and program SoftDevice S132 (memory range: 0x0 - 0x1F000)
2. Keil uVision -> develop a project from example using \pca10040\s132\arm5_no_packs\xxx.uvprojx

3.                 -> keep the default memory settings (IROM1: 0x1F000, 0x61000, startup; IRAM1: 0x20002128, 0xDED8) an
   

4.                 -> downloading program using J-Link debugger at default settings
   

Now I'd like to use the rigDFU and followed the instructions from Rigado:

1. get back to the factory settings of the BMD-300: S132 v2.0.0 (memory 0x0 - 0x1c000) and rigDFU v3.2.0 (memory 0x75000 - 0x7FFFF)
2. generate the image.bin from the .hex file produced by uVision and try to load over serial connection as explained in the rigDFU datasheet
3. despite the fact that the process seems to be successful (see the command prompt capture prompt.png), the application doesn't work

I suppose that the memory settings of my application don't match the requirements of the DFU and/or I should work with another pack in uVision...

Can someone give me some hints about where to start or which example to follow?

Thanks a lot for the great nordicsemi support!

if you're developing against a softdevice which uses 0x1f000 and then changing that to one which uses 0x1c000 then you're using a different softdevice from that you're developing against. Surely the rigado eval board uses the same version as the module.

[Sébastien Schiesser]

yes it uses the version 2.0 (using 0x1C00)...

I first tried to change the start address in uVision, as well as the size to 0x2B000 (the rigDFU datasheet gives these values for the user application space) -> compiled & load well but didn't work.

I also tried to install the "correct" SoftDevice (2.3.0 I think) -> same thing.

Basically I miss a link for setting up the correct environment in order to develop with rigado DFU at factory settings...

Do you know the rigado bootloader start address? Please post the current IROM and IRAM settings in Keil of your application.

[Sébastien Schiesser]

As posted in the question:

• bootloader starts at 0x75000
• IROM: start 0x1C000, size 0x2B000 (previously default was: 0x1F000, 0x61000)
• IRAM: start 0x20002128, size 0xDED8

You are compiling your new application against the SoftDevice headers that corresponds to the SoftDevice present on the Rigado Module? If the SoftDevice ends at 0x1C000, then it sounds like its a S132 v2.0.x SD, but it could sound like you've compiled your application against a S132 v3.x.x SD.
