STM32-MAT Script Fixes:

1. Comment line 256: fprintf('\n### Code Format : %s\n',buildOpts.codeFormat);
buildOpts.codeFormat doesnt exist, the execution of this line throws an error and halt the code generation. I'm using Matlab 2019a, Windows 10 1803 x64, Stm32CubeMX 4.25 and STM32MatTarget_4.4.2_setup.exe
2. Search for "extModeIocUsartUpdate" and add "ioc_info = ioc_parse(ioc_path);" in the next line.
   Note: this is a potential bug, the script creates a new ioc file if it cant find an existing one, but it doesnt read the new ioc file after creation.
3. Comment below (around line 164):

            cset.set_param ('ExtMode','on');            
            cset.set_param ('ExtModeTransport',0); 
            cset.set_param('ExtModeMexFile','ext_serial_win32_comm');

1. File > New > CCS Project -> Empty Project (with main.c)
2. "Project Property" -> Resource -> Linked Resources, add a variable: INSTALLROOT_F2837XD = ${COM_TI_C2000WARE_SOFTWARE_PACKAGE_INSTALL_DIR}\device_support\f2837xd.
3. "Project Property" -> C/C++ Build -> Settings -> Tab "Tool Settings", in "C2000 Compiler"/"Include Options", add an include path: ${INSTALLROOT_F2837XD}/headers/include, this includes all headers which contains all register definition. Add an include path: ${PROJECT_LOC}/inc, this folder will be populated with headers copied from TI's demo.
4. "Project Property" -> C/C++ Build -> Settings -> Tab "Tool Settings", in "C2000 Compiler"/"Predefined Symbols", define a macro: CPU1
5. "Project Property" -> C/C++ Build -> Settings -> Tab "Tool Settings", in "C2000 Linker"/"File Search Path", add a search path: ${INSTALLROOT_F2837XD}/headers/cmd, also a add a library file: F2837xD_Headers_nonBIOS_cpu1.cmd (--library, -I).
6. Create src and inc folder i

In order to save space on the SPI flash, SquashFS + JFFS2 should be used.

1. Download tools: ResourceHacker and mssstyleEditor, then unpack them
2. Download resources: Win8 theme for Win10, and then uppack it, we will need 'Windows 8 RP Themes for Windows 10\Theme\Themes For 10 Build 14393 Anniversary Update\Windows 8 RP\aero 8 RP.msstyle'.
3. Open it with ResourceHacker, export IMAGE 1055:0 and IMERSIVE 1:0.
4. Make a backup of the original aerolite.msstyles and make a copy of it to your working folder (arbitary)
5. Open it with ResourceHacker, Go to 'Action -> Add an Image or Other Binary Resource' or hit Ctrl+M to open the "Add Binary Resource" Dialog. Choose the menu image resource file that is going to be used, then change the "Resource Type" to IMAGE and resource name to be what ever available, in my case, 993.
6. Change the value of IMERSIVE 1:0, by importing the data from "aero 8 RP.msstyle"

In this configuration, DHCP will run on the OpenWrt Box, while the TFTP server (the one serves the boot files) runs on a different computer.

1. Add to /etc/config/dhcp on OpenWrt Box

config boot linux
        option filename 'pxelinux.0'
        option serveraddress '192.168.?.?'
        option servername '?'
