At reset the rom bank select was set to follow addr[16:15] until IDE was activated by a write to any IDE reg. After that it reflects the value of the rom_bankSel register On a new board with no driver yet in flash this switch would not be triggered, causing the driver to be written to the wrong bank of flash. Now the switch will flip on any write to the boards range, the flash identification step will trigger this.

Ordering PCBs
You can find the latest Gerbers attached to the latest Release
I recommend ordering from JLCPCB as this board was designed within their 2-layer specifications
BOM and Placement files for JLCPCBs assembly service are provided and can be found inside the Gerbers folder and the Gerbers.zip file found under Releases
Recommended options when ordering:
- Thickness: 1.6mm
- Surface Finish: ENIG-RoHS
- Gold Fingers: Yes
- 45°finger chamfered: Yes
