Hi all.
I have a problem with all GPIO and LED  in  ON mode. can anyone help me for resolving the problem?.

Hi,

It looks like an interesting little board... From what I can see in the logs, it has 4MB Flash/32MB SDRAM.

Can you give us more details: where did you purchase it, at what price? Do you have pinout, schematic, manuals, etc?

Regarding your problem, can you provide more information: what firmware do you run, which patches... What is the problem exactly: you can't drive GPIOs because they are all declared as LEDs?

That is an interesting board.  Hope there is a model available with 8MB flash. 

On the row of pin headers at the bottom to the right of the USB connection I can make out "I2C" and "SCLK" and "SD", but can't read many of the rest of the labels.  I think perhaps SPI is brought out.  Can you provide a higher resolution photograph of those labels.

I see from the log that console is assigned to ttyS1--is ttyS0 brought out anywhere?

Is there a datasheet available?

My fault: this baby has 8MB Flash, not 4MB as I stated above!

Please tell us where to get it!!!

thank you for interesting
Here is the schema of gpio.

I'm doing the documentation

if not configure the gpio in this manner,  all GPIO start in HIGH state. to start them in default LOW I need to change uboot?.

the micro board in a few weeks will be on sale.

static struct gpio ayyar_gpios[] = {
    { 1,    GPIOF_IN,        "GPIO 1" },
    { 2,    GPIOF_IN,        "GPIO 2" },
    { 7,    GPIOF_OUT_INIT_LOW,    "GPIO 7" },
    { 8,    GPIOF_OUT_INIT_LOW,    "GPIO 8" },
    { 9,    GPIOF_OUT_INIT_LOW,    "GPIO 9" },
    { 10,    GPIOF_OUT_INIT_LOW,    "GPIO 10" },
    { 11,    GPIOF_OUT_INIT_LOW,    "GPIO 11" },
    { 12,    GPIOF_OUT_INIT_LOW,    "GPIO 12" },
    { 13,    GPIOF_OUT_INIT_LOW,    "GPIO 13" },
    { 14,    GPIOF_OUT_INIT_LOW,    "GPIO 14" },
};

Thanks for the response.  The pinout descriptions and latest photo seem to be of the "Ralink 802.11n AP Router Module Board AWM002".  Are you, or is your company, designing the board that the module plugs into?

This looks like a very nice board to act like a "little computer" (including wifi), and it should be useful for many tasks.

I'm not expert by any means, but I would not think that uboot would be setting the GPIOs high.  To test that, if you interrupt the boot by pressing "4", are the GPIOs high at that point?  It would make much more sense for them to be initially low, or floating.

I agree with you. in the uboot.  the gpio are set to HIGH.
is possible to patch it in LOW mode?

Initializing GPIOs with no specific purpose to OUTPUTs is stupid!

It is better to define them as TriState if possible, (so they are disconnected from incoming signals) or INPUTs if not possible, so that they don't provoke any disaster upon reboot: just imagine one of the GPIO declared as output is connected to a switch triggering the launch of a balistic missile

Then, in the hardware board design, you can still fix the default state for each GPIO if required by using pull-up or pull-down resistors.

Yeah, this is AsiaRF's AWM002 module!

It could have been designed to be a little bit more compact by using dual-Ethernet jacks and magnetics or even integrated MagJacks.

Switch S1 is labeled "GETWAY/APCLIENT" instead of "GATEWAY/APCLIENT"

It could be made even more interesting by adding an AU6350MGL USB hub/SDCard combo chip to get a microSD card to mount as a FS and up to 3 USB host ports.

As usual, I would be surprised to see that the module or the main board are RoHS/CE/FCC compliant.

And of course, it all depends on the price... Getting both the module and the main board for < 30USD is the real challenge!

the initialization of the GPIO have been set as PCM, I2S, I2C.

I'm no expert on the subject. but I hope it can be resolved through software

No, you should let the user decide! Even if you can label the corresponding GPIO on the PCB for their recommended function, their application is up to the user, so let them as inputs, then provide a way to switch to the desired configuration: what if I want a full UART, i.e. no PCM/I2S on the multiplexed pins?

Yes, but again, the user will put pull-up/pull-down resistors as required by the application, but the software should not force a GPIO to output in U-Boot or in the kernel: this should be up to the user, maybe using a web-based config tool.

this ralink microboard is very good.
i want to buy 1 to play around
anybody can tell me how to order this in USA?

More interesting if you share the SDK files
