Support calculate CRC by Srecord¶

Install¶

On Linux

sudo apt install srecord

On Window: Download Srecord to install

Arguments to bash script¶

PROJ_NAME=$1
BUILD_DIR=$2
SREC_PATH=$3
TOOL_CHAINS=$4
START_ADDR=$6

For example:

$ bash sl_iec60730_cal_crc16.sh "${PROJ_NAME}" "${BUILD_DIR}" "C:\srecord\bin" GCC "0x8000000"

Or if you want to calculate multiple regions:

$ bash sl_iec60730_cal_crc16.sh "${PROJ_NAME}" "${BUILD_DIR}" "C:\srecord\bin" GCC "0x8000000 0x8000050 0x80000a0 0x80000f0 0x8000140 0x8000190"

[!NOTE] If you calculate multiple regions CRC, you need to enter the start and end addresses of each zone. For example, in the above command, srec will calculate a three-range CRC: 0x8000000 - 0x8000050; 0x80000a0 - 0x80000f0; 0x8000140 - 0x8000190.

Path ${BUILD_DIR} have the files *.bin, *.hex, and *.s37. A *.map file is also needed in this directory, so that bash can check to find the address of the check_sum variable to store the calculated CRC value.
