Example Description
|
|
|
|
This loopback example describes how to use Ameba SDIO device APIs in spdio_api.c and spdio_api.h.
|
|
|
|
How to build:
|
|
1. copy src\main.c to project\realtek_ameba1_va0_example\src
|
|
2. include lib\lib_sdiod.a for build, then re-build the project
|
|
|
|
Requirement Components:
|
|
PC (running Linux kernel over 3.13) * 1
|
|
Ameba EVB * 1
|
|
|
|
Pin assignment for SDIO device on Ameba EVB:
|
|
--------------|----------------|-----------------------
|
|
GPIO Pin name | SDIO pin name | Pin name on Ameba EVB 3V0
|
|
--------------|----------------|-----------------------
|
|
GPIOA4 | SD_D0 | D5
|
|
-------------------------------------------------------
|
|
GPIOA5 | SD_D1 | D2
|
|
-------------------------------------------------------
|
|
GPIOA0 | SD_D2 | D17
|
|
-------------------------------------------------------
|
|
GPIOA1 | SD_D3 | D16
|
|
-------------------------------------------------------
|
|
GPIOA2 | SD_CMD | D7
|
|
-------------------------------------------------------
|
|
GPIOA3 | SD_CLK | D6
|
|
-------------------------------------------------------
|
|
GND | GND | GND
|
|
-------------------------------------------------------
|
|
|
|
Set-up:
|
|
1. Connect Ameba to PC via SDIO slot
|
|
2. build this example and upload firmware to Ameba EVB
|
|
3. build iNIC host SDK and run loopback test (refer to Run Loopback test.docx in iNIC source)
|
|
|
|
Behaviour:
|
|
PC sends loopback packet to Ameba and Ameba will send back to PC whatever received
|
