Hi there,
I am getting the subject line error and understand that my ".const" size has exceeded the size of 1 Flash Bank sector. Each sector size is 0x1000 and my compiled .const size is apparently 0x1004. See memory allocation screenshot below. I am doing a bunch of print type statements where I think the text is consuming a lot of memory.
To fix this issue I tried increasing the allocated flash size with the line: .const : >> FLASH_BANK0_SEC11| FLASH_BANK0_SEC12 | FLASH_BANK0_SEC13 | FLASH_BANK0_SEC14, ALIGN(8)
(Please see my complete linker file at the bottom of this question)
This does not fix the error even though there is more than enough memory allocated (4 sectors). I think it may have something to do with contiguous requirements / Align (8) ? Is there something I can modify in the linker / program file to split this across the multiple free sectors?
Thanks in advance for your help,
