AWR2944: The AWR2944 has a 5-second delay during the startup phase.

Roy Zhuang

Part Number: AWR2944

Hi team,

The customer found in previous projects when using XA2944BD that after importing HSM, they needed to increase clockP_sleep(1000U) to 4000U for the code to run normally, otherwise there would be a 5-second delay stuck between load HSM and SBL.

Currently, when the customer uses AWR2944BS, after importing HSM and setting clockP_sleep to 4000U, there is still a probability of experiencing a 5-second delay stuck before SBL. And current remains at 139mA. Has the team encountered this issue internally? The SDK and chip versions are as follows:

SDK version is 4.6.1.02 + 09.02.15, and the AWR2944 model is shown in the figure.

Hi Samhitha,

Is there any information to sync on this issue? Or do you need me to provide additional information?

Hi Roy,

We have not seen such observation internally. Could you help me understand the following things:

1. Which SBL the customer is using at their end? is it the default SBL provided by TI or their own custom SBL?

2. do they have any custom hsmRT or using TI provided TIFS hsmRT?

3. how are you saying that there's a 5msec delay here? where exactly you are measuring the time?

4. In case it's a custom sbl and hsmRT, are you using any TRNG services in the code?

Regards,

Shruti
