MSP430F5259: CRC_CHECK using BSL Scripter

Akshit Viradiya

Part Number: MSP430F5259

Hi,

I am working on project which has msp430f5259 chipset ,

I usually do programming chipset using BSL Scripter, so now i need to verify my program flash properly or not .

So basically i put CRC_CHECK command in script file with start address of code memory and total bytes of memory need to calculate CRC.

But when i give total bytes which is more than 0xFFFF it shows error calculating CRC , it says max CRC calculating size is 0xFFFF bytes

Is there any solution to calculate more than 0xFFFF bytes CRC, bcz i need more than 1,18,000+ bytes calculation which is nearly 0x1D000 in hex

Hi,

Can we separate it into two sections for CRC check. One is from 0x0000 to 0xFFFF and another one is from 0x10000 to 0x1D000.

Hi Cash,

no 0xFFFF means total bytes not address of memory so,

as of now i used to separate total memory bytes into four lengths and do CRC check process like

CRC_CHECK 0x00A400 0x8000 // (0x00A400 is start memory address , 0x8000 total bytes from start memory address need to be CRC check)

CRC_CHECK 0x0012400 0x8000 and so on

But i think it's not useful because at the end we all need Total CRC value to check our program verification and it is not done in this separate CRC check, it's only gives every 8000 bytes crc of every start memory address and we need 1,18,000+ bytes CRC value

Hi,

I know but the CRC check command is only write for less than 0xffff bytes. No other proper way to improve it.

Hi Cash,

Yes it's negative point for us.

thanks for your guidance.
