Thank you for your response and the two very helpful links!
I hesitated upgrading the firmware before having a positive
feedback with a specific firmware version.
Just for a bit of redundancy, I'll list the update procedure (from
00.03.05.04.00 to
00.03.06.00.00) I performed, from above links:
- Pressed power button
- As soon as all LED were lit, pressed AND let go of the [Help]
button within 1 second. - [Single] button was now lit, nothing else.
- Inserted USB stick (no partition, FAT32, DS2000Update.GEL in root)
- [CH1] button flashed during update
- When update was done, a bunch of LEDs lit up, but no
LEDs were flashing - Removed USB stick
- Power cycled
My MSO2302A didn't like my 1 GB Kingston USB stick with
1 FAT32 partition, but gladly accepted my 2 GB BASF USB
stick without any partitions, just freshly FAT32 formatted
(
mkfs.vfat -F32 /dev/...), with the file "
DS2000Update.GEL"
copied to its root folder.
And after the power cycle, the help images were repaired!
