Cannot initialize EVAL-AD7606B-FMCZ (no-OS project)

Hi,

Can you double check that you selected the desired interface in hw, hdl and no-OS?
For hdl check: AD7606X HDL Reference Design [Analog Devices Wiki]
For HW look at the user guide section(JP5) EVAL-AD7606B-FMCZ Evaluation Board | Analog Devices

Andrei

Thank you for your advice.
I have checked hw, hdl, and no-OS.
By switching on S1 (all three switches) on EVAL-AD7606B and modifying device_id and dout_format in common_data.c as follows, initialization was successful.

struct ad7606_init_param ad7606x_init_param_parallel = {
.axi_init = &ad7606x_axi_init_param,
.gpio_reset = &ad7606x_gpio_reset,
.gpio_convst = NULL, // Driven by HDL
.gpio_busy = NULL, // Driver by HDL
.gpio_stby_n = &ad7606x_gpio_stby,
.gpio_range = &ad7606x_gpio_range,
.gpio_os0 = &ad7606x_gpio_os0,
.gpio_os1 = &ad7606x_gpio_os1,
.gpio_os2 = &ad7606x_gpio_os2,
.gpio_par_ser = &ad7606x_gpio_ser_par,
.device_id = ID_AD7606B,
.oversampling = {
},
.sw_mode = true,
.parallel_interface = true,
.config = {
.dout_format = AD7606_4_DOUT,
},
.digital_diag_enable = { // CRC checks
},
.offset_ch = {
},
.phase_ch = {
},
.gain_ch = {
},
.range_ch = {
{ -5000, 5000, AD7606_SW_RANGE_SINGLE_ENDED_BIPOLAR },
{ -10000, 10000, AD7606_SW_RANGE_SINGLE_ENDED_BIPOLAR },
{ -5000, 5000, AD7606_SW_RANGE_SINGLE_ENDED_BIPOLAR },
{ -10000, 10000, AD7606_SW_RANGE_SINGLE_ENDED_BIPOLAR },
{ -5000, 5000, AD7606_SW_RANGE_SINGLE_ENDED_BIPOLAR },
{ -10000, 10000, AD7606_SW_RANGE_SINGLE_ENDED_BIPOLAR },
{ -5000, 5000, AD7606_SW_RANGE_SINGLE_ENDED_BIPOLAR },
{ -10000, 10000, AD7606_SW_RANGE_SINGLE_ENDED_BIPOLAR },
}
};

However, a new error has arisen.

-1ERR: ../ad7606x-fmc/src/basic_example.c:92:main(): Error getting samples.

This error seems to be arised in "transferring data using DMA."
Should I further modify common_data.c or other files?
Can you give me advice?

Hi,

I would look at that line:
no-OS/projects/ad7606x-fmc/src/basic_example.c at main · analogdevicesinc/no-OS
Firs, maybe comment it. Then see why does it fail, probably a bad device setting. Not sure that this code was tested on for all supported devices.
From the name basic_example, I presume not.

I stopped testing in parallel mode for the time being, and tested in serial mode.
The serial mode was successful with the modification of common_data.c described above.
The make option for HDL was "INTF=1 NUM_OF_SDI=1."
Thank you.
