Hi, i am trying to modify a Soc in which the original company shut down. It is a vital part of several industries and would be great if we could get it going again. The great thing is all that needs modified is a static string stored in memory. I have found and located this string and updated it accordingly. At the end of the line I made sure to update the CRC. However I am having issues now with getting the entire files CRC correct. I have tried using the Hex Workshop CRC calculator but i keep getting the error of "Hex File parsing failure. Checksum of Main Flash does not match Hex Checksum record". I would love some help here. Thank you so much!

From what I understand, you are trying to modify the hex file of a PSoC 4 device without rebuilding the project. The procedure to calculate the checksum of the hex file/modify the hex file is proprietary and I do not think Infineon supports that.
