Command Line Interface not giving feedback

Hi,

Your board seems to run u-boot or Linux instead of the no-OS project.

What HDL/no-OS branch did you use? Did you follow these instructions: https://wiki.analog.com/resources/no-os/build for building the project?

Thanks,
Dragos

Hi Dragos,

I'm using the master branch and have Vivado 2020.1. 

The reference you linked is the one I'm looking at. Below is a copy of my CMD commands and outputs.

After your U-boot comment I tried swapping the headers for JTAG programming on the Zedboard, but that resulted in nothing coming out of TeraTerm once programming was finished and the blue LED came on.

I also found the link below which makes no reference to changing the headers so I don't believe changing them is necessary.

Thanks.

Hello michael.gibson,

From your log, I can see that your build completed sucessfully and the .elf file was uploaded on the board.

What's the exact issue? You are not able to see anything on the serial output?

Are you properly connected to the UART port? From your screenshot above it looks that you have proper setup for the serial port (115200 baud rate)

You can optionally use (after the build is done) the `make develop` command to open an SDK instance and start debugging your project.

Regards,

Antoniu

Antoniu,

I'm having the same problem.  After I execute the "make run" I get the following on my UART port then it no longer responds to any input.

[1B][0;31mzynq>[1B][m

U-Boot 2011.03-dirty (Jul 11 2012 - 16:07:00)

Using default environment

Out:   serial

Your board is booting u-boot instead of the no-OS project - if inserted, try to remove the SD card.

Thanks,
Dragos

Here's what I tried:

1) power down

2) remove SD Card

3) power up

4) rerun "make run";  the elf file uploaded to board as before

5) same problem; no response at all on the UART port

Can you put the board into JTAG boot mode and try again? I believe all the jumpers need to be in GND position.

-Travis

OK. Tried that as well.

1) power down

2) Change jumpers to JTAG boot mode (all in GND position)

3) power up

4) make run; [00:00:00] ad738x_fmcz.elf uploaded to board

5) same problem

Sorry, this is the actual response:

I would still like an explanation for the following during the make:

Hi,

Please make sure your no-Os repository is up to date. It looks like the run command is building the project instead of uploading the elf file.

Hi,

Sergiu

Thanks.  My repository is up to date since I just started over from scratch.

Please answer these questions.

1) Do you have these boards (AD7134 and zedboard) to try this code?

2) Can you confirm that my make output is as expected, including missing files and errors? (see below)

Hi Steve,

As I see in the code in the master version of the project (https://github.com/analogdevicesinc/no-OS/blob/master/projects/ad713x_fmcz/src/ad713x_fmc.c) you don't need to interact with the code it will just print data, or if you enable TINYIIOD (how to enable tinyiiod) you can connect using IIO Osciloscope.

My recommendation are:

Open a windows cmd with administrator privileges in the project folder.

Run a `make clean_all` in order to start from a clean workspace.

Then run `make update_srcs` this will just create an sdk project you can edit.

Run  `make develop` : will open xsdk with the created projects.

Program the fpga from the sdk.

Set a breakpoint at main and then debug.

Are you able to see data from the first printf?

Regards,

Mihail

Mihail,

I did as you suggested.  The result is the same.  I get as far as this instruction on line 209 in ad713x_fmc.c, which fails every time.

    ret = ad713x_init(&ad713x_dev_1, &ad713x_init_param_1);

Here is the output from CMD:

NOTE that I'm still getting errors during the final link process.  I've asked several times if these errors are expected, but no one has answered this question.

Yes, the output of the terminal is normal. They are xilinx bsp related warnings.
Can you step inside the ad713x_init function and see which function fails, there seems to be many thinks that can fail.

Yes, it's failing in spi.c on line 57 and returning FAILURE

int32_t spi_init(struct spi_desc **desc,
         const struct spi_init_param *param)
{
    if (!param)
        return FAILURE;

    if ((param->platform_ops->init(desc, param)))
        return FAILURE;

    (*desc)->platform_ops = param->platform_ops;

    return SUCCESS;
}

Do you have the same hardware to try this on (AD7134_EVAL and zedboard)?

Some of these parameters look suspect.  Can you confirm they are correct?

Hi Steve,

For this platform, the device id and bit order parameters are irrelevant.

Also 0x989680 in hex is the same as 10 000 000 in decimal which represents the 10mhz sclk speed.

You could try debugging a bit deeper and go inside the param->platform_ops->init(desc, param) function (that should go to https://github.com/analogdevicesinc/no-OS/blob/master/drivers/axi_core/spi_engine/spi_engine.c#L623 ) and see exactly where the code is failing.

Sergiu

The device_id was causing the failure for both of these commands.  I changed them both to a value of 01 and the init function no longer fails.

ret = ad713x_init(&ad713x_dev_1, &ad713x_init_param_1);

ret = ad713x_init(&ad713x_dev_2, &ad713x_init_param_2);

However, I believe this causes later issues since the first read from spi returns 0x0.  What is the correct device_id to use ?

Now that I'm past that error, here's the next issue...failing ad713x_spi_reg_read...line 106 of ad713x.c..
