LP876242-Q1: LP876242 NVM configuration template

Hi Lei,

IF from SPI to I2C can only be changed by creating new NVM configuration.

Can I ask you why are doing this? Is this some kind of temporary change that you want implement or would this be permanent change?

Best regards,

Hi Ishtiaque，

This is permanent change for only I2C IF in our design. I tried to define a NVM configuration early based the blank template this week, but the PFSM is too  complex to pass PFSM validation. 

So I want to make this change at the LP87624 dedicated NVM configuration for Dual MMIC and AM2732.

Thanks!

Hi Lei,

What is the Dual MMIC? is it AWR2243 or different? if it is the AWR22343 then that can support SPI and so AM2732. So why still there is need to change interface. 

Have you looked at our reference design https://www.ti.com/tool/TIDA-020047  for the dual MMIC and with AM2732. 

Best regards,

Hi Ishtiaque，

The application is Dual AWR2243 and Serializer (only support I2C IF), and we know the reference design https://www.ti.com/tool/TIDA-020047  for the dual MMIC and with AM2732, so we think you have the corresponding NVM configurations for the reference design.

Thanks!

Hi Ishtiaque，

Yes, we have contacted with local sales representative.

Toady, we generated a NVM configuration（.bin file, Static configurations and PFSM), when using this configuration to Program Device, always on the interface below. Is there any problem with the static configurations?

Thanks！

Hi Ishtiaque，

Could you please give us the I2C/SPI SEL registers, address and value. We try to find the difference after change the IF from I2C to SPI:

SERIAL_IF_CONFIG——I2C_SPI_SEL——Value I2C：

"id": "I2C_SPI_SEL",
"value": "0",
"staticConfig": true,
"isTouched": true

SERIAL_IF_CONFIG——I2C_SPI_SEL——Value SPI：

"id": "I2C_SPI_SEL",
"value": "1",
"staticConfig": true,
"isTouched": true

Hi Lei,

Please send us your email to send you the bin file. That would be easier and let the further support be continued if needed.
