Hello,
I am currently using Medium Range Radar laboratory and I need to use the external flash memory to store some variables in the external QSPI flash. I know that this memory is share among different actors, therefore, is there any memory map to know how is divided the memory? Which is the starting address to store user application data?
Considering the Technical reference manual I understand that I can use the following section:
Regards.

Hello Cesar,
What I see in my postBuildStep matches with the documentation that you referenced:
However, my doubts are more related to how is divided the flash memory and how is being used. I am using Medium Range Radar as main application and CAN SBL as bootloader. And I need to know how is being used. As I read in the forum, I have 2MB of the flash memory for the 4 Meta Images, therefore it could be something like this?
I see that CAN SBL defines SBL_METAIMAGE_OFFSET to 0xC0040000, so it looks like my calculations are not correct...
Where can I find this information?
Regards,
Javier
Hello,
I think that we have found the answer, but it is a pity that we have to dive into dozens of documents until you find what you are looking for.
Taking as reference the IWR6843 Bootloader Flow it is explained how is divided each Meta image:
Therefore, I supposed that everything after Meta Image 4 is free space that can be used for the application. Excluding the end of the flash which is used for configuration.
