Hi team

Customer used to use C2000, the generated hex file include the first line 020000040000FA, but there is no first line in M0 Hex file.

question is: what's the function of this line? why M0 hex file do not have the first line? CCS version is 12.5

Hi Joe,

This line is used for higher 16bit address.

020000040000FA

First 02 is data lengh

Second 0000 is lower 16 bit address

Third 04 is the type, '04' means Extended Address(higher 16 bit address)

Fourth 0000 is the data, means higher 16 bit address

Last FA is checksum

If the higher 16 bit is 0000, then it is not necessary.

Hi Yuhao

Thanks and nice to meet you in E2E.

To align the hex format with previous SW version, customer want to know whether there is a set up in ccs to make hex file keep this header, no matter it is necessary or not.

Thanks

Joe

Can you check the configuration of Arm Hex Utility? And you can compare the C2000 project and M0 project.
