Prepare BIN file in embARC
Launching embARC with U-Boot

U-boot can be used with embARC on HSDK.

Note:

embARC 2017.12 (or higher) and ARC GNU 2017.09 (or higher) are required.
MicroSD card is required.
Make sure U-Boot image version is Prebuilt Linux Distribution for ARC HS Development Kit (HSDK), 2018.01 (or higher). Go to U-Boot Image Recovery in On-Board SPI-Flash to update U-Boot image on HSDK.
Visit Getting Started with embARC Software with GNU Tools to prepare embARC software.
Visit Launching Baremetal Application on HSDK to launch baremetal application on HSDK.

Launching embARC Application on HSDK

Prepare BIN file in embARC

Change to <embARC_root>/exmaple/freertos/net/ntshell and type the following commands in the command line.

make TOOLCHAIN=gnu BOARD=hsdk BD_VER=10 clean
make TOOLCHAIN=gnu BOARD=hsdk BD_VER=10

Type the following command to generate BIN file.

make TOOLCHAIN=gnu BOARD=hsdk BD_VER=10 bin

Note:

The ntshell example is used here in exmaple/freertos/net/ntshell. The same build and run steps are useful for other examples on HSDK.

Launching embARC with U-Boot

Rename BIN file app.bin. Copy it to a MicroSD card and insert it to the HSDK card slot.
Connect HSDK board to the host with USB. Open terminal emulation program to view UART output from HSDK. The switch Boot Image should be 0x1 to locate boot image in the on-board SPI flash. Press RESET to reset the board and hit any ket in the terminal to stop autoboot.

Type following commands step-by-step. Make sure the BIN file path is correct

hsdk# fatload mmc 0 0x80000000 app.bin

hsdk# run hsdk_hs38
hsdk# setenv core_entry_0 0x80000004
hsdk# hsdk_init
CPU start mask is 0x1
hsdk# hsdk_go

Launch the embARC application after typing hsdk_go in the terminal.
