RE: confusion on boot loader settings

Thank you, Håkon Alseth ! Your way might work well. I set IROM1 from 0x3B000, size 0x4800 and IRAM1 from 0x20002000, size 0x2000. It compiled properly. My concern is the reason why I got m_boot_settings[] incorrectly if it is initialized without "const" restraint.

Hi,

It seems that you found the solution to your issue, and you're verifying that setting the array m_boot_settings[] as a const is ok. I did a quick check, and the generated .hex is equal.

Since this is an array that is located in flash, declaring the array is "const" is the proper way. However, there is an issue with the Keil project settings when setting the array to "BANK_VALID_APP". The Keil linker seems to be a bit confused and complains that you're exceeding the IROM size.

Workaround: We have set the size of the image incorrectly. If you set the IROM1 Size to "0x3C00" it should compile properly:

Cheers, Håkon
