Regression: BlueSCSI v2 firmware breaks boot on Amiga 2000 with GVP HC+8 Series II

[AmigaCoding]

Hi,

I’m experiencing a regression with newer BlueSCSI v2 firmware on the following setup:

Amiga 2000
GVP Impact A2000-HC+8 Series II (SCSI controller)

Working firmware
2024.12.08-rel → works correctly (system boots)

Failing firmware
2026.03.01 or 2026.04.27 → system does not boot. After a while, I get the kickstart screen.

Configuration (bluescsi.ini)
[SCSI]
System="Generic"
EnableSCSI2=0
PrefetchBytes=0
WiFiSSID=Andromeda
WiFiPassword=mypass

[SCSI0]
Vendor=Blue
Product=Bluedrive
Version=1.0
SectorsPerTrack=32
HeadsPerCylinder=1

Do I need to adjust any new parameters in bluescsi.ini for compatibility with the aforementioned GVP controller?

Update:
A different HDD (OFS) image works fine on the new FW. The one that doesn't work on the new FW is my 1080 MB image with partitions formatted as PFS3. As mentioned in the previous post, this image works fine on FW Version: 2024.12.08-rel.

Can it be that SectorsPerTrack=32 and HeadsPerCylinder=1 are no longer correct for this image? The image that works on any FW is 50 MB in size (OldFileSystem).
