Other Parts Discussed in Thread: TMS320F28377S, SYSBIOS
Hi.
I'm building a project with an TMS320F28377s C2000 processor and the ti/rtos stack.
I ran into this problem adding a large task we want to execute:
[C28xx_CPU1] ti.sysbios.family.c28.TaskSupport: line 114: Stack (0x11080) not located on PAGE 0 (stack must be located entirely below 0x10000)
I mapped the .ebss section to dataram 0xc000 -> 0x1bfff and my .map file shows

for some reason the .ebss is quite large (above 0x7000) so moving the .ebss somewhere else won't fit. But the new task (RTOS_MScreen.c) gets placed first in the available space...
Is there a way for me to tell the compiler to place the taskStackSection first ?
Or i have some large arrays i use to store data. I suppose this is why the .ebss is this large. Is there a way to link these arrays somewhere outside .ebss?
