I’m Getting a white screen after BenF V3.64 upgrade?
It started when I went to do the upgrade. I did not have it in the “Device Firmware Upgrade” mode and put the file in the drive letter that the device created E:\ (e-Design DSO Flash Disk USB Device)
But the drive did not disconnect and reconnect to change the file extensions. From .hex to .rdy .err
So I disconnected it and reconnected with no change???
I should have noticed that it was not in the upgrade mode, but I did not. Turned device off and back on…. Bright white screen. I it sit there for a few min with no change. Turned it off and went to do it again, and but this time I booted into the Upgrade mode. That screen worked fine. Booted into the device info screen, it worked fine also. So I am back into the upgrade screen this time I get drive letter E: (DFU V3_26_D). I copied the files for BenF and the drive disconnected and reconnected file names changed ok everything looks good??? Reboot device white screen!!!
So I used the only other Firmware I had, DSO Nano 2.6 firmware booted into upgrade mode copied file it disconnected and reconnected Files extensions changed, ok reboot. . .
Gray (vertical bars of white and black) Screen
Frantically looking for another firmware and found the one on the Seeed Sudio Product page. So I attempted to use the file from there. Booted into the upgrade mode copied the DSO V4 file The drive disconnected and reconnected, disconnected and reconnected, disconnected and reconnected, that’s strange??? After 4 times opened the drive and the file name changed “DSONAN~1.RDY” ok reboot. . .
I get a gray (alternating lines of black and white) screen that flashes the seeed studio logo upside down and in reverse color (logo background in white letters in black)
When I press buttons the screen flickers like it does when it changes menus. It seems like it’s working but I can’t see anything but the gray screen . . . the random flashing stops when you press the hold button
Thinking for some reason it may be the files that were left in the drive you get in normal operating mode E:\ (e-Design DSO Flash Disk USB Device) I connected it to USB a window pops up and tells me the drive is not formatted or there is no drive plugged in??? and the fist time it poped up it wanted to format it to a capacity of 6.42 GB I closed the window, disconnected and reconnected same thing drive must be formatted tis time 2.27 GB??? Closed the window . . . turned the device off and started this thread
