Run Bootloader from RAM

I think I've gained some more insight as to what needs to be done to run from RAM.

Changes need to be made in the linker file as well. The MEMORY directive section I took from the example

MEMORY
{
VECTORS (X) : origin=0x00000000 length=0x00000020
FLASH_API (RX) : origin=0x00000020 length=0x000014E0
FLASH0 (RX) : origin=0x00001500 length=0x0005EB00 //LS04x and RM42 Flash size is 0x60000
SRAM (RW) : origin=0x08002000 length=0x00006000 //LS04x and RM42 SRAM size is 0x8000
STACK (RW) : origin=0x08000000 length=0x00002000

}

The SECTIONS directive section I also took from the example (with slight modification)

SECTIONS
{
.intvecs : {} > VECTORS
flashAPI :
{
..\Debug\source\Fapi_UserDefinedFunctions.obj (.text)
..\Debug\source\bl_flash.obj (.text)
--library= F021_API_CortexR4_BE.lib < FlashStateMachine.IssueFsmCommand.obj
FlashStateMachine.SetActiveBank.obj
FlashStateMachine.InitializeFlashBanks.obj
FlashStateMachine.EnableMainSectors.obj
FlashStateMachine.IssueFsmCommand.obj
FlashStateMachine.ScaleFclk.obj
Init.obj
Utilities.CalculateEcc.obj
Utilities.WaitDelay.obj
Utilities.CalculateFletcher.obj
Read.MarginByByte.obj
Read.Common.obj
Read.FlushPipeline.obj
Read.WdService.obj
Async.WithAddress.obj
Program.obj > (.text)
} load = FLASH_API, run = SRAM, LOAD_START(api_load), RUN_START(api_run), SIZE(api_size)
.text : {} > FLASH0
.const : {} > FLASH0
.cinit : {} > FLASH0
.pinit : {} > FLASH0
.bss : {} > SRAM
.data : {} > SRAM
.sysmem : {} > SRAM
}

This leads me to 2 questions:

1) I can't follow the syntax of the "flashAPI: ..." excerpt above. Is this taking the F021_API_CortexR4_BE.lib library, and the text sections of those various object files, and calling this now the flashAPI section? Then in the bootloader application, we must copy over the flashAPI section with _copyAPI2RAM_() or a similar function?

2) I'm getting build warnings "#10068-D no matching section" for the following three lines, and I can't seem to figure out what that means.
..\Debug\source\Fapi_UserDefinedFunctions.obj (.text)
..\Debug\source\bl_flash.obj (.text)
--library= F021_API_CortexR4_BE.lib < FlashStateMachine.IssueFsmCommand.obj...

Thanks

Hello matt,

I will have one of our Flash API experts to help you on this.
