Introduction[edit | edit source]
Axel Lite requires a dedicated adapter to be plugged to the AxelEVB-Lite carrier board. This adapter:
- provides the SODIMM socket for the AxelLite SOM
- provides the following additional features:
- microSD slot (for SD boot)
- JTAG connector
- dip-switch for boot mode selection
- routes the signals from the AxelLite pins to the AxelEVB-Lite mating connectors
The following images show the top and bottom views of the AxelEVB-Lite-Adapter:
Connectors' pinout[edit | edit source]
J6 - SODIMM connector[edit | edit source]
J6 is a TE Connectivity 204-pin SODIMM socket. The pinout matches the Axel Lite pinout.
J1, J2, J3 - AxelEVB-Lite mating connectors[edit | edit source]
J1, J2 and J3 are Hirose FX8C-140S-SV connectors that match the AxelEVB-Lite SOM connectors' pinout.
J4 - JTAG[edit | edit source]
J4 is a SAMTEC FSI-110-03-G-S connector. The following table reports the connector's pinout:
| Pin# | Pin name | Function | Notes |
|---|---|---|---|
| 1 | DGND | - | - |
| 2 | JTAG_TCK | - | - |
| 3 | JTAG_TMS | - | - |
| 4 | JTAG_TDO | - | - |
| 5 | JTAG_TDI | - | - |
| 6 | JTAG_nTRST | - | - |
| 7 | CPU_PORn | - | - |
| 8 | N.C. | - | - |
| 9 | N.C. | - | - |
| 10 | JTAG_VREF | - | - |
J5 - MicroSD[edit | edit source]
The signals of the SD1 interface are routed to the J5 microSD memory card connector. The following table reports the connector's pinout:
| Pin# | Pin name | Function | Notes |
|---|---|---|---|
| 1 | SD1_DAT2 | DATA[2] | - |
| 2 | SD1_DAT3 | Card Detect/DATA[3] | - |
| 3 | SD1_CMD | CMD line | - |
| 4 | ADP_3.3V | Power Supply | - |
| 5 | SD1_CLK | Clock | - |
| 6, 9, 10, 11, 12 | DGND | - | - |
| 7 | SD1_DAT0 | DATA[0] | - |
| 8 | SD1_DAT1 | DATA[1] | - |
| 13 | ADP_3.3V | - | Pull up to 3.3V with 10K Ohm - |
Boot mode selection[edit | edit source]
S1 is a 2-way dip switch for the boot mode selection. The following table reports the available configurations:
| Switch | Position | Function | Notes |
|---|---|---|---|
| S1.1 | N.C. | - | - |
| S1.2 | ON | AxelLite SD/NAND: boot from SD AxelLite SPI/USB: boot from USB |
- |
| S1.2 | OFF | AxelLite SD/NAND: boot from NAND AxelLite SPI/USB: boot from SPI |
- |
