It means I filled the entire flash with zeros, then Platform-tools restored it sucessfully.
Below is the result of restortion of the filesystem using platform-tools when the entire flash was filled with zeros.
1. in a HEX-editor 138412032 bytes were filled with 0x00, saved in a file «00 flash 132MB dump.bin», posted here
2. copied the file «00 flash 132MB dump.bin» to dsoflash order, renamed to „restore.bin“
3. using dsoflash write.bat wrote the „restore.bin“ to the flash memory, a copy of command promt window posted here
4. using dsoflash read.bat read the flash memory to the backup.bat file, compared to «00 flash 132MB dump.bin», the files were identical
5. restored the file system using platform-tools 2022.07.07_fpga_3205: 3 errors, the device did not start, black screen
6. using dsoflash read.bat read the flash memory to the backup.bat file, renamed to „00 platform-tools-David-2022.07.07_fpga_3205_ read.bin“, posted here
7. examened the „00 platform-tools-David-2022.07.07_fpga_3205_ read.bin“ in a HEX-editor. The resalts posted here.
So, this test shows that the platform-tools was unable to restore the file system if the entire flash memory was filled with 0x00.
