Hi,

 

  We are working with BF525 processor, There we want to generatye an .ldr file.

 

Already we are having a InitCode for BF532 processor, we just modified that to BF525 processor(I am attaching that file(InitCode)here..) Will that be correct? or is there any difference from that? When we use that modified Initcode for BF525 to generate the ldr we got the format in a different way(I am attching that ldr(test) here..).. We are using SPI slave and ASCII format for generating the ldr...Please check it once and help me

 

 

 

And one more problem is for programming the Atmel SpI we are using some code for BF532, the same code we have modified for BF525 > when we are reading the data it is reading as 0  and after some time it is showing some error saying that

 

"Target halted due to software breakpoint but no breakpoint found at address: 0xef000744
    Possible reasons are:
    1.An embedded breakpoint (EMUEXCPT instruction) in the code
    2.A breakpoint is placed at the last instruction of a do() loop
    Warning: External memory is disabled for this region of memory.
    Warning: External memory is disabled for this region of memory."

 

 

and all the sdram memory allocations are resetting to "DD".  I am attching my code here,please check it once and tell me what could be the problem,we are using PG1 for booting the spi flash
