During serial programming of MB9BF568R the FLASH MCU programmer erase the working flash sector starting from 0x200C0000.
I've searched out for some FLASH MCU programmer setting, but nothing.
Is there a way to perform serial programming without erasing data flash memory?
Thanks
Mauro

No easy way to remain the content of working flash sector starting from 0x200C0000, as the serial programming flow of tool FLASH MCU programmer is fixed.

It points to the file named "m_flash.9b560r".
No way to modify it?

Hi,
I think you are wrong:
If you are using the "Flash MCU Programmer for FM", then ...
1) Using the button 'Full Operation' will only perfrom a sector erase of those sectors that are used within your Hex-File
'Full Operation' will automatically connect (Download Kernel) to your device, perfrom Sector Erase of sectors described by HEX-File, Program and verify your Hex-File.
Hence 'Full Operation' will not erase Work-Flash as long as Workflash is not used within your Hex-File.
2) Using the button 'Erase' will perform Chip-Erase, what will erase complete Flash.
Please use always option (1), 'Full Operation' to erase only Flash sectors that are used by your hex-file.
Alternatively you can have a look to the 3rd party tool FLASHly, www.holgerium.de/elektronik -> flashly,
that allows programming of your device by command line. Also here you can erase sectorwise.

Hi Holger,
thanks for the answer.
Unfortunately the stand alone erase operation and the "full operation" erase has the same effect: Chip-Erase.
The third-part programmer download link seems not working.
Any other suggestion?
Thanks
