Why does fflash require an actual device to calc CRC?

JPB_plxs — Wed, 22 Aug 2007 22:21:55 GMT

When trying to calculate a CRC for a given S-Record file, why does fflash need have CCS connnect to an actual device?

Example usage: fflash 56835x_flash.cfg whatever.S -crcP0x0:0xffff -dumpvirtual

According to the fflash PDF for the -crc option: "This can be used in conjunction with the -dumpvirtual to dump the 32-bit CRC of a file without loading it onto the device."

If the file is not being loaded to the device, why require a CCS connection?

Hi,

You're right.

I reproduced it on my side.

It appears that the fflash check in first the connection to the CCS.

For sure this is not required when -crc and -dumpvirtual options are using.

I think it's more a design issue of the tool.

I must check it with the engineer.

Can I suggest you we continue to follow this issue via the CRM system ?

Can you please log it in CRM ?
