Hi Tony,

Unfortunately As of today this seems to be the case.
I tried to do a CPU reset and system reset but that does not seem to help. The only thing that works is a POR.

You can program a SBL to bypass running the loadjs everytime.

Refer to Getting started-> EVM Setup ->Flash SOC Initialization Binary for the MCU+ SDK (https://dev.ti.com/tirex/explore/node?node=AAItjAZOtq4dV64ZMMvr3g__rN4Qml4__LATEST)

Rajat,

How do you think what is the reason?

Hi Tony,

In my opinion it may be due to the fact that DDR, memories and peripherals are not reset due to CPU reset.

Let me check this internally.
