Demo Kits#
| Name | Product # | Board # | Description |
|---|---|---|---|
| DK AM62L DC OSM-S 2GB/32GB | 50099106 | 40099 339 | Demo Kit (dual core, 1250 MHz, 2 GB RAM, 32 GB eMMC) |
The bootloader is expected at the following offsets:
- SD card boot: 0k (
0x0000) - eMMC boot: 0k (
0x0000)
eMMC configuration for booting from eMMC (Linux commands):
# set 8-bit boot bus interface
mmc bootbus set single_backward x1 x8 /dev/mmcblk0
# enable the mmcblk0boot0 partition with ack
mmc bootpart enable 1 1 /dev/mmcblk0
Kontron reserved area on extended OTP Memory#
The first 400 physical bits (bit 0 to 399) of the extended OTP are reserved
for special usage by Kontron. These locations are already programmed with
appropriate content and can't be used to store customer values! In the write
view they cover row 0 to 15, in the read view MMR 0 to
12. The image below illustrates these areas

The Row and Field Bits columns are the write view — a row is programmed as a
whole with fuse prog and is 25 bit wide. The MMR column is the read view:
fuse read returns memory mapped registers of 32 bit, so MMR n covers the
physical bits 32n to 32n+31. Because the two grids do not line up, a row
usually spans two MMRs. See
Fuse Configuration for extended OTP on TI AM62L
for how values are programmed and read back.
Customer data may start at physical bit 400, which is row 16 for writing and
MMR 13 for reading.
Layout and Connectors#
Digital IOs#
Four digital inputs/outputs are available. The table below shows number and function of available DIOs and their associated GPIOs.
Each DIO has one GPIO that switches a MOSFET driver against the supply (24V) rail and another GPIO to read back the voltage level via a resistor divider.
The GPIOs are provided by a GPIO expander which is connected via I2C.
| DIO Name | Function | GPIO Label | GPIO Device | GPIO Offset | Connector |
|---|---|---|---|---|---|
| DIO1 | drive | DIO1_OUT |
gpiochip2 | 0 | X1501 - Pin 1 |
| DIO1 | read | DIO1_IN |
gpiochip2 | 1 | X1501 - Pin 1 |
| DIO2 | drive | DIO2_OUT |
gpiochip2 | 2 | X1501 - Pin 3 |
| DIO2 | read | DIO2_IN |
gpiochip2 | 3 | X1501 - Pin 3 |
| DIO3 | drive | DIO3_OUT |
gpiochip2 | 4 | X1501 - Pin 5 |
| DIO3 | read | DIO3_IN |
gpiochip2 | 5 | X1501 - Pin 5 |
| DIO4 | drive | DIO4_OUT |
gpiochip2 | 6 | X1501 - Pin 7 |
| DIO4 | read | DIO4_IN |
gpiochip2 | 7 | X1501 - Pin 7 |
