... I used a USB pen drive that I always used to use to install expansion packs/additional styles/install previous firmware updates. Just to verify, the pen drive that I'm using is in "FAT32" format which was detected by the keyboard. Is there any format that I should use? ...
Hi Christopher,
external data media (USB sticks)
must be FAT32 formatted so that yamaha keyboards can work with them.
It is NOT absolutely necessary to format a USB stick that is already fat32 formatted directly on the keyboard. But it is still
recommended.
There are basically two different types of USB sticks:
1.
Almost all USB sticks are displayed on the computer as "Removable Disk".
2.
Some sticks (this is very rare) are displayed on a computer as "Local Disk" (just like an internal hard disk).
- The
first type of stick can be used on the keyboard for ALL purposes (including firmware updates).
- The
second type of stick can be used on the keyboard for all "normal" purposes, but NOT for Firmware updates (!) However, as mentioned, this second type of stick is very rare to find.
So it could happen (in very rare cases) that a stick with which you have already worked successfully on the keyboard suddenly does NOT work for a Firmware update (if you want to use it for a Firmware update
for the first time). In this case, it helps to just use a different stick.
In YOUR special case, the last description is definitely NOT the reason for the malfunction, because you had written that you had previously successfully carried out Firmware updates with this stick.
MY guess is:Since "PSR-SX900" is displayed, but the boot process does not continue, the
Linux kernel is obviously still started properly ("Linux Initramfs starting"). The error then occurs during the "Linux Rootfs starting" phase ("Rootfs corruption"). Due to the "SX900 System Boot Flowchart" this indicates an error (maybe data corruption) on the internal memory module "eMMC0"(8 GB). Unfortunately, only the authorized Yamaha service will be able to help you here.
Best regards,
Chris
