Building the Non-Trust Zone Project

2.4.2.1 Compile Project on Cygwin
1) Open "Cygwin Terminal"
2) Direct to compile path. Enter command "cd /SDK/project/realtek_amebaz2_v0_example/GCC-RELEASE"
3) Clean up pervious compilation files. Enter command "make clean"
4) Build all libraries and application. Enter command "make all"

2.4.2.2 Generating Image Binary
After compile, the images partition.bin, bootloader.bin, firmware_is.bin and flash_is.bin can be seen in different folders of \GCC-
RELEASE.
1) partition.bin stores partition table, recording the address of Boot image and firmware image; located at folder
\GCC-RELEASE;
2) bootloader.bin is bootloader image; located at folder \GCC-RELEASE\bootloader\Debug\bin;
3) firmware_is.bin is application image; located at folder \GCC-RELEASE\application_is\Debug\bin;
4) flash_is.bin links partition.bin, bootloader.bin and firmware_is.bin. Located at folder \GCC-
RELEASE\application_is\Debug\bin.
Users need to choose 'flash_is.bin' when downloading the image to board by PG Tool.
2.4.2.3 Download
After a successfully compilation and 'flash_is.bin' is generated without error, user can either
1) Directly download the image binary on to demo board from Cygwin (as below)
Connect SWD to board and open "JLinkGDBServer.exe". Please refer to 2.2.1 Jlink for SWD connection.
