AFE7950EVM: Issues in dynamic parameter configuration of AFE using CAFE Library

Noumeer Piracha

Part Number: AFE7950EVM

Tool/software:

I want to dynamically configure the parameters of the AFE using the CAFE library. To achieve this, I followed the document "Implementing the CAFE Library in Vitis."

I copied the CAFE library's header files into the include folder of my project, and the source files into the Src folder. I then updated the read, write, log, and delay functions accordingly.

Next, I used the AFE.saveCAfeParamsFile() function in the AFE79xx software to save the afe79xxParameters, and replaced the contents of the init_tiAfe79DeviceInfo_t structure with the newly generated file, as shown below:

void init_tiAfe79DeviceInfo_t()
{

	afe79SystemParamsStruct systemParams = {

Then in main, included the header files and instantiated the AFE structure like this

afe79InstDeviceInfo tiAfe79DeviceInfo_t= {0}; //Instantiating the AFE Structure
init_tiAfe79DeviceInfo_t (&tiAfe79DeviceInfo_t); //Loading the parameters into the AFE Sysparams Structure 
AFE79FNP (setAfeLogLvl) (&tiAfe79DeviceInfo_t, 2); //Setting log level

Then called the checkdevicehealth() function like this,

uint16_t allOk = 0;
AFE79FNP (checkDeviceHealth) (&tiAfe79DeviceInfo_t, &allOk); //This function Reads the complete device health and returns it as a pointer.
xil_printf("allOk: %d\r\n", allOk);

Its output is;

Then called readRxNco() function like this:

uint8_t ch_no = 1;
uint8_t band =  1;
uint8_t nco = 0;
uint32_t read_nco_freq = 0;
AFE79FNP (readRxNco ) (&tiAfe79DeviceInfo_t, ch_no, band, nco, &read_nco_freq);

Its output is;

I have configured NCO frequency of this channel as 9Ghz but it read as 82Khz. Can you please guide me what's the issue.

Similarly when I update the NCO using following code;

		uint8_t ch_no = 1;
		uint8_t band =  1;
		uint8_t nco = 0;
		uint32_t nco_freq = 9200000;
		uint32_t read_nco_freq = 0;

		AFE79FNP (updateRxNco ) (&tiAfe79DeviceInfo_t, ch_no, nco_freq, band, nco);

Its result is as follows;

Could you please guide me on where I might be wrong?

Hi Nourmeer,

Just to confirm, before running the check device health have you configured the AFE using a generated log file from Latte? If you clear the errors and read again do you continue to see the PLL lost lock in the past error?

Please note that a log or hex file must be generated by Latte and this will be used to configure the AFE. It is not possible to modify the AFE configuration by modifying systemParams structure. To confirm that the system params structure has been update

In regard to your other issues, have you confirmed that the systemParams are correct in the structure?

Can you try using the following format for the contents of the 'tiAfe79_afeParameters' file (Only replace line 4 with your contents)?

void init_tiAfe79DeviceInfo_t(AFE79_INST_TYPE afeInst)
{

	//Place the systemParams structure from the file generated by the AFE.saveCAfeParamsFile fucntion here.

	afeInst->afeSystemParams =systemParams;
}
