-------------------------------------------------------------------------------
This folder contains a sample Linux application that allows command line
interact with CAPE devices through public I2S and GPIO interface.(This tool
also can run in Windows. When it runs in Windows, it communicate with CAPE
device through Siena interface instead ).
-------------------------------------------------------------------------------
USAGE
-------------------------------------------------------------------------------
Usage: cxdish <options> [command]
Available options:
-h, --help this help
-D, --device STR specifies the i2c device path, default is '/dev/i2c-0'
-r, --reset GPIO_NUM specifies the RESET GPIO pin number, default is '184'
-a, --address I2C_ADDRESS specifies i2c address, default is '0x41'
-d, --debug LEVEL specifies device level from 0 to 2
-W, --max_write specifies max writing lenght,default is , max= 4000
-R, --max_read specifies max writing lenght,default is , max= 4000
-L, --legacy enables legacy mode flash for legacy device
-H, --hot_flash download image during firmware is running
-d, --debug enables i2c dump
-v, --version prints cxdish version
-q, --quiet enables quiet mode
Available commands:
sendcmd STREAM_ID COMMAND [arg]
flash SFS_FILE [BOOTLOADER]
set-mode MODE
get-mode
fw-version
# Examples #
1. Read tool version.
./cxdish -v
2. Read firmware version.
./cxdish fw-version
3. enable i2c dump. likes
./cxdish fw-version -d 1
4. send command to tool.
./cxdish -d 2sendcmd 0xB32D2300 0x00000004 0xd74c2d00
5. upgrade the firmware.
./cxdish -r 148 -D /dev/i2c-1 flash oem_image.sfs iflash.bin
6. get current mode.
./cxdish -r 148 -D /dev/i2c-1 get-mode
7. set mode.
./cxdish -r 148 -D /dev/i2c-1 set-mode CONF
8. change max writing length to 60 bytes during flashing
./cxdish -r 148 -D /dev/i2c-1 -W 60 flash oem_image.sfs iflash.bin

BUILDING THE SAMPLE
-------------------------------------------------------------------------------
It requires Compiler toolchain or GNU G++ to build the code.
To compile this, simply type 'make' to build the code.
$make
-------------------------------------------------------------------------------
RUNNING THE SAMPLE
-------------------------------------------------------------------------------
Linux platfrom:
Usually, i2c devices are controlled by a kernel driver. can't be controlled by
usermode application. Please make sure kernel enable the following options.
CONFIG_I2C_CHARDEV=y
CONFIG_GPIO_SYSFS=y
CONFIG_SYSFS=y
Windows platfrom:
It communicate with communicate with CAPE devices through Siena interface. Please
connect Siena to PC and make sure the Siena driver is installed properly before
running the tool.
