IAST Scope:
Integration of TI MCAL driver to Vector stack.
Initial Ethernet communication up and running.
There is no proper handling of the watchdog or P2 times during the erase operation by TI driver leads to failure in SW Download, updated the driver and informed the TI for formal release.
Understanding and integrating SBL SW from TI to our environment as per our use case.
Compile the SW as per DDR memory map and load the SW from ROM to RAM during run time.
Configuration and handling of feature response after reset in ethernet network, challenged faced because unlike CAN in ethernet we have to close the tcp connection before reset and reopen the connection after reset, and need to sync with the tester to make sure Socket connection is open and response is sent after the connection is established.
Key Challenges on Architecture:
After power on SW will be loaded from External NOR flash to External RAM.
SBL will copy BM to RAM location.
BM will copy either FBL/APP/Updater to RAM location before giving control to respective targets.
Application download and Diagnostics are done via Ethernet interface. Network management is handled via CAN.
Information like application validity, SW version etc are stored in external NOR chip communicated via I2C.
For debugging purpose used UART interface to print useful information during run time.
