Custom Flash Loader for XCORE-200 Topic is solved

[ffomich]

Hi,

I try to migrate custom flash loader from my XS1-U8A-128 based board to new XE216-512 based board.

Flash loader analyze button state and load Factory or Upgrade firmware image from flash.

Code: Select all

#include <c:\Program Files (x86)\XMOS\xTIMEcomposer\Community_14.1.2\target\include\xs1.h>


int dpVersion;
unsigned int imgAdr;

unsigned buttonPort = XS1_PORT_4E; //TODO: set correct port

int portMask = 0x01; //TODO: Set correct port mask for button pin

void init ( void ) {

    unsigned buttonVal;
 
    // Read state of button
    asm volatile("setc res[%0], %1" : : "r"(buttonPort), "r"(XS1_SETC_INUSE_ON));
    asm volatile("in %0, res[%1]" : "=r"(buttonVal) : "r"(buttonPort));
 
   // Now 'buttonVal' will have the button value

   // If button is pressed - load factory image. dpVersion: 0 - factory image, 1 - upgrade image
   dpVersion = (buttonVal & portMask) ? 0 : 1;

}

int checkCandidateImageVersion ( int v) {
	return v == dpVersion ;
}

void recordCandidateImage ( int v, unsigned adr ) {
	imgAdr = adr ;
}

unsigned reportSelectedImage ( void ) {
	return imgAdr ;
}

Make with command:

Code: Select all

xcc -c loader.xc -o loader.o

Create file for flash:

Code: Select all

xflash --factory image.xe 0x10000 --loader loader.o --boot-partition-size 0x40000 --target-file target.xn -o flash_image.bin --noinq --verbose

And get error:

Code: Select all

Please help.

Hi ffomich,

Is it possible that the compiler has compiled it for XS1 rather than XS2?

I normally pass loader.xc directly to xflash - rather than compile it first; that way xflash sorts it all out.

Cheers,
Henk
