Part Number: TMS320F280025
Dear Team,
I create an output section named USER1 in the main.c file. I want to assign this section to a fixed address rather than an address range.
__attribute__((section(".user1"))) const STORE_MSG_t STORE_MSG =
{
0xffffffff
};
I tried using the method in this link. TI Linker Command File Primer

It looks like this in the map file.
But the compiler gave a warning.
Description Resource Path Location Type
#10456-D You must specify the page for the specific placement of ".user1" when not using unified memory model. 28002x_generic_flash_lnk.cmd
How do I specify a page for user1?
Best regards
Enya
