[ECOS] Regarding loading of application on to Flash

[Hariprasad B]

Hi All,

I am trying to load my program in to the Flash(ROM) & it gives the error as follows
Platform: SE77X9 (SH 7729)
Copyright (C) 2000, 2001, 2002, Red Hat, Inc.

RAM: 0x0c000000-0x0c800000, [0x0c0061a0-0x0c7ed000] available
FLASH: 0x81000000 - 0x81200000, 32 blocks of 0x00010000 bytes each.
RedBoot> load -m xmodem
CEntry point: 0x0c020000, address range: 0x0c020000-0x0c065a84
xyzModem - CRC mode, 10301(SOH)/0(STX)/0(CAN) packets, 2 retries
RedBoot> fis create application
Invalid FLASH image size/length combination

But again when I try to load a simple one threaded application it works fine.Can anyone help me out for what could be the problem.

Thanks & Regards

Hariprasad

It is telling you that the size of the flash area already reserved for
"application" it smaller than the size downloaded.

This is pritty obvious when you read the code:

   // 'length' is size of FLASH image, 'img_size' is actual data size
    // Round up length to FLASH block size
#ifndef CYGPKG_HAL_MIPS // FIXME: compiler is b0rken
    length = ((length + flash_block_size - 1) / flash_block_size) * flash_block_size;
    if (length < img_size) {
        diag_printf("Invalid FLASH image size/length combination\n");
        return;
    }
#endif

        Andrew
