WL1837MOD: ODP Process parameter

We are checking with our HW team and get back.

Thanks

Hi Ping,

Can you share the data you collected from the commands?

Thanks,

Hi Vincent,

Below HCI_VS_Get_System_Status command read. All those return parameters rea are usual except OPD.

I think the UART connectivity is ok.

[INFO] software version XZ: 0x0820

[INFO] chip version : 0x20

[INFO] in TI mode

[INFO] Root frequency 26000

[INFO] using external slow clock

[INFO] Process Type is Nominal

[ERROR] ODP Process not Nominal

[INFO] Deep Sleep Mode : 0x00

[INFO] Whitening Mode : 0x00

[INFO] CDC enabled

[INFO] frequency hopping : 0

[INFO] UART baud rate : 115200

[INFO] temperature index : 7

[INFO] temperature in Celsius : 33

[INFO] I2C status : 0

[INFO] txco frequency 6590

Thanks & regards,

Hi,

Please see here: https://link.springer.com/article/10.1007/s10836-011-5215-x

Looks like ODP allows us to detect issues insidehe device - Were these devices modified or damaged in any way? You can also request a HW review in case you think your HW is causing the issue here: www.ti.com/.../WILINK-DESIGN-REVIEWS

Hi Vincent,

Sorry that I cannot access the article.

Could you specify what is the physical meaning on ODP process detected with Weak & Strong?

Best regards,
