5. Check the
DOS .bat file “generate_config_cFile.bat” and add your newly created
custom configuration source files at two locations:
•
Calling python to execute them
•
Using the .hex files created from the last step in the parameter list of the
call to the converter.py utility, which generates the configStream.c
source file.
6.
Open cmd.com (DOS box) and navigate to the project’s subdirectory, where the
config files are located.
7. Execute the batch script. A new version of NXP_SJA1105P_configStream.c is
created, overwriting the old one.
8. Rebuild the project
6.4 Wakeup and Sleep
The SJA1105SMBEVM hardware allows applications to send the board to sleep mode,
and to get woken up either by a remote wakeup command received over one of the
communication links, or by a local event, represented by a pushbutton. A simplified
schematic is shown in Fig 18.
Fig 18. HW support for wakeup and sleep applications
During board sleep mode, most of the components are powered down, except the PHYs
and the CAN transceiver, which use VBAT (or 12V0) to maintain some minor activity, but
also shutting down the major part of the chip during sleep. Powering down the
components is implemented by disabling the three switching power regulators for the
5V0, 3V3 and 2V5 power rails.
