AFE7900: About config

?? ?

Part Number: AFE7900

Hi,

I am configuring the afe7900 using fpga. During configuring the 0x79 Opcode , the MACRO_ERROR_IN_EXECUTION is set. But I can't find the reason in the document SBAU337. And I can't even find the instructions about 0x79.Please tell me what to do next.

Thankyou

Regards

add the value of 0xF2~0xF7. I have a doubt, why did miso pull up after reading f7?

After the MACRO_ERROR_IN_EXECUTION is set， I did a rewrite operation； Now 0x79 can Configuration successful，but 0x13 keep failing；

As for this problem, it has been solved. Some registers are incorrectly configured.

Hi Beijie,

The opcode, 0x79, that you mentioned is for the JESD configuration. The opcode, 0x13, is the power up calibration. If issues are occurring for these you should check power, clock, and SPI writes.

Was the issue you found caused by the generated log or an issue using the log?
