Hello

I want to test the crc flash .so want to change the program area flash.

how to do it?

Hi Whong,

I don't suggest to change the content of the flash. If you want to test the crc algorithm, you can do it by increasing or decreasing the pattern count by 1 (64-bit).

Hello

I want to test whether the flash error exception during running can lead to the safe side.Not a simple algorithm for calculating CRC

How can we create flash exception.

You can inject a single-bit or double-bit flash ECC error. Please use fmcECCcheck() as an example.

Hello

but if that ,the value of my crc64 flash can be changed? I want to change the calculated crc64 value,

why don't you suggest me change the flash bit.Can I directly change the value of program area flash address

Hello,

If the 1 bit ECC is flipped, the CRC64 will be change since the single-bit ECC error is corrected, which means the data is changed.. If 2-bit ECC bit are flipped.

It is impossible to change 1-bit flash data.

Hello

Thank you

If the 1 bit ECC is flipped, the CRC64 will be change since the single-bit ECC error is corrected.why the CRC64 will be change?Dose flash changed? Is it because of ECC changes?

Is there no way to change the flash in the program? Is it okay to write a value to the address in the program
