Thanks a lot for helping me
But it seems not to work, and I dont know why.
The version I have is:

I ‘ve tried to upgrade the version with this steps:
1. Get a USB key in FAT32 (I’ve tried FAT16 also) and put in the root directory the firmeware:

I have tried to put it directly in d:\bin\stoneHMI.bin too without any results.
Can I use any USB FLASH DISK ? I’ve tried several ones too….
2. I put the switch at the back to HOST

3. I plug my USB Disk
4. I Start the LCD Panel
And then, nothing happend. The normal display windows is there and the firmware is not loaded!
What am I doing wrong?
