As a workaround, copy correct CRC pattern from the HEX file to the CHEKSUM segment definition defined at the end of the startupstm32xxxx.s modified assembly file (KEIL compiler case), or directly at segment placing the check sum result at linker script file (GCC compiler), and recompile the project with the correct CRC pattern copy after. This output for original firmware Scan Time: 11:23:35 This table is used to calculate the CRC32 value in a fast way. You dont have to do anything with the CRC32 polynomial table, because it means only that binwalk found a CRC32 table in the boot loader. What's New in Structure Viewer (version 4.I have this Ubiquiti firmware and I successfully extract the firmware and rebuild it, I modify Squashfs filesystem and rebuild it using build-firmware.sh script from firmware-mod-kit, but the problem I have is CRC Not the same as the original value, so how can I bypass CRC checksum also what is this "CRC32 polynomial table, big endian" If you modify the firmware and rebuild it, then the CRC values should be changed.What's New in Structure Viewer (version 4.92).Select the type of CRC to compute: either 16-bit or 32-bit.Enter the algorithm initial value, polynomial and XOR out constants.
