I'm trying to flash an NHS3100 via NFC. When I use the "NHS31xx Downloader" app it works fine.
Now I would like to do the same with an NFC reader. For this purpose I have adapted the python script, otherwise it won't work with the current python version. The script is already running now, I can connect to the NHS and download the file. But I have the problem that there is something wrong with the CRC, the bootloader always returns an error code here.
I would need the data of the CRC algorithm which should be used, and if possible a bin-file with the CRC for checking my calculation. The file does not need to be a running firmware for the NHS, any file with dummy data would be sufficient.
