Issue Summary

Enhancement

In document, the example command for iotdk is like this:

$ gmake BOARD=iotdk BD_VER=10 CUR_CORE=arcem9d TOOLCHAIN=mw LOCATION=eflash bin

LOCATION=eflash has no effect to makefile, need to modify this.

Do you know how to let bootloader downloaded into eflash?

step 1:

generate a bootloader.bin file witch can run in eflash.

add APPL_DEFINES += -DUSE_APPL_MEM_CONFIG in makefile.

add 

#ifdef BOARD_IOTDK
#define REGION_ROM  REGION_EXT_ROM
#endif

in appl_mem_config.h

run command make BOARD=iotdk bin to generate bootloader.bin file and copy it to SD-Card in iotdk board.

step 2:

use flash cmd in ntshell to write bootloader.bin into eflash.

undo the changes in makefile, run command make BOARD=iotdk run.

run command in ntshell flash -eflash bootloader.bin.

then reset the board.

Sorry, I did not fix this problem: The command I used: First ,I modified the makefile and changed the USE_MCUBOOT=0, because USE_MCUBOOT=1 will prompt error Second I add APPL_DEFINES += -DUSE_APPL_MEM_CONFIG in makefile. I did not modified the appl_mem_config.h ,because it cannot find REGION_EXT_ROM When I did like that, it compiled good.But.... I copyed the .bin to my SDcard ,and made run successfully,and press the reset button ,and It didn't work. This is the error: **COM1>embARC Build Time: Aug 31 2020, 04:54:56 Compiler Version: Metaware, Clang 9.0.1 FatFS initialized successfully! boot.json open error. use default bootloader

Press any button on board to stop auto boot in 5 s . . . . . Start loading 0:\boot.bin from sdcard to 0x20000000 and run... led out: f, ff** Could you please help me ?
