completely.

FIRMWARE UPDATES
To make firmware updating as easy as possible, a boot loader is used.
Copy the new version of the firmware to the root directory of an SD card and insert it.
The boot loader will automatically detect the new firmware and writes it into the Flash memory of
the controller. This process is indicated by rapid flashing of the LED.
.
CAUTION: Only use the firmware images available on our website!
Cause
No supply voltage to SD2IEC.
The device address is set incorrectly or the con-
nections on the IEC connector are
incorrect.
The SD card is incorrectly formatted. In rare cases,
the SD card is incompatible.
The contrast is not set correctly or the display con-
nector is not properly inserted.
Faulty connection of the disk change button or the
button is permanently suspended.

Remedy
Check connections from the SD2IEC to the C64,
in particular, the lines for VCC and Ground (GND).
Check the setting of the device address.
Check the connecting cable solder joints at the
C64 IEC socket are clean and correctly assigned.
If possible, format the SD card in FAT32 format
without the quick format option or use an SD card
formatter tool.
Alternatively, use another SD card.
Adjust the contrast using the
potentiometer on the SD2IEC board.
Check that the display connector is correctly posi-
tioned
Check the connection of the DiskChange button
and the push-button itself. You can
test the DiskChange function of the SD2IEC tem-
porarily by manually touching the stripped ends of
the relevant wires together on the CTRL cable.
