nrf5_SDK secure bootloader with external QSPI Flash Image

[Dominik Eugster]

Hi

I am working with the SDK secure bootloader from the SDK 17.1.0. The generated encrypted zip package we transfer with DFU and the APP and this is working great. The application image is too big to use the dual image feature. We have an external flash connected with QSPI and already implemented the possibility to receive and store the same zip package in this external QSPI flash.

Now we have to change the secure bootloader to read the new zip file content from this external flash in the bootloader and not over the BLE DFU feature. To get this feature, I checked the QSPI_booloader project in the examples folder (examples\peripheral\qspi_bootloader\pca10056\blank\ses) but can't see where this project is using the bootloader features like to check the CRC, the crypto key and all other features like in the secure bootloader project. Or is the idea to use this project to implement the start address to the existing secure bootloader project and this code will start reading from the external flash instead of the received files from the BLE DFU connection?

Is there an existing sample how to implement this feature in the secure bootloader project?

Thanks a lot for inputs, Dominik

Hi

This seems to be a linker issue. Can you upload the exact error message you're seeing on your end, maybe as a log file so we can get some context? Please check out this case, where my colleague Vidar explains a bit about the flash placement file (flash_placement.xml) and how to define the additional memory segments in your project. My guess is that by increasing the bootloader size the bootloader settings page has also been increased, and that where this is stored no longer fits in the allotted memory.

Best regards,

Simon

Problem for the compiler error was the following:

I had to use the 2 variales as extern in the QSPI part.

Now I'm testing and check the features of the Nordic original BLE DFU and also teh QSPI functions. There the crypto cehck is not included but this I will add from the BLE DFU Bootloader.

extern nrf_dfu_settings_t s_dfu_settings;
extern uint8_t m_dfu_settings_buffer[CODE_PAGE_SIZE];

Hi

Did adding 2 variables on your QSPI resolve the previous build error? If so, do you now have another issue when building your project, or does it now build successfully? I don't see anything in your build log referring to an issue with the crypto.

Best regards,

Simon

Hi

The building is ok now thanks, no eroor. I only mentioned that I like to add the crypto functions to the QSPI part like the original bootloader is using for the BLE DFU with Crypto feature.
