6.3.5. 66AK2G02 ICE EVM Hardware Setup¶

6.3.5.4.1. Setting Boot Switches¶

The DIP switch (SW3) is used for selecting the boot mode.

For the EVM Out-of-Box experience, use SD/MMC boot mode as shown in the image below:

The table below lists all of the boot modes supported on the ICE EVM.

6.3.5.4.2. Connecting an Emulator¶

The EVM supports two types of emulation via the on-board XDS100 emulator or the 20-pin JTAG header.

When an external emulator is not connected to the 20-pin JTAG Header, the on-board XDS100 embedded JTAG emulator is the default type of emulation (SoC JTAG signals are routed to the XDS100 on-board emulator). When an external emulator is connected to the 20-pin JTAG Header, it is automatically detected and the SoC JTAG signals are routed to the external emulator.

On-board XDS100 Emulator

The K2G ICE EVM has on-board XDS100 embedded JTAG emulation circuitry so an external emulator is not required. Users can connect to the target SoC via CCS by connecting the USB cable, supplied in the ICE EVM kit, as shown in the image below.

20-pin JTAG Header for Connecting an External Emulator

Users have the option of connecting an external at the 20-pin JTAG Header connector (EMU1). The 20-pin JTAG Header is provided on-board for high speed real-time emulation. All JTAG and EMUxx signals are terminated on 20-pin JTAG Header.

6.3.5.4.3. Powering Up the EVM¶

Power Supply Specifications

The K2G ICE EVM can be powered from one of two sources. A single +24V / 2.5A DC (60W) external power supply connected to the DC power jack (J6). In addition, the K2G ICE EVM can be powered from the 12V supply pins on the PCIE edge connector. A power ANDing circuit is included in the design which will prevent damage if the +24V is connected while the board is installed on a PCIE backplane. The +24V supply will supply the power for the board in that condition.

6.3.5.5.1. Update CCS to Install Keystone II Device Support Package¶

All revisions of the board require this step to be performed in order to get the latest GEL files and the target content for the K2G if you are using CCSv7.0 and earlier. This step will not be required for CCS versions higher than version 7.1. CCSv7.0 or CCSv6.1.3 package contain KeystoneII device support package v1.1.6 which doesn’t contain K2GICE specific target files hence we recommend this update.

1. All CCS v6.1.3 or CCSv7.0 and earlier version users are required to update the Keystone Device Support package by going into the Help->Check For Updates

2. Select Keystone2 device support package. Follow menu options to continue with the update.

3. After the update is complete go to Help->Installation details and check that Keystone2 device support package v1.1.9 or later are installed as shown below.

6.3.5.5.2. Connect without an SD Card Boot Image¶

Configuring target configuration files

Launch CCS and create a new target configuration (File->New->Target Configuration file) as shown in the images below.

Provide an appropriate name to the configuration. Select Spectrum Digital XDS100 emulator and target as K2G ICE EVM.

In advanced settings, make sure that the GEL files are populated correctly. The following GEL files and their corresponding cores are provided below.

• C66X Core: icek2g.gel
• A15 Core: icek2g_arm.gel

Connecting to target

1. Download Code composer Studio or for CCSv7.0 and earlier, ensure it contains Keystone device support package version 1.1.9 as described in the how to guide “Update CCS to Install Keystone II Device Support Package.”

2. 66AK2G02 ICE EVM contains boot switches to configure for “No boot/sleep” mode. So configure the boot switches to “No Boot Mode” as described in the “Setting Boot Switches” section.

3. Connect an XDS100 Emulator to the XDS USB port of the ICE EVM as shown in the section “Connecting Emulator.”

4. Launch CCS and create a new target configuration as discussed in the previous section “Configuring target configuration files.”

5. Launch the newly created target configuration.

6. K2G can be a DSP or an ARM master boot device so connect to the C66x or the A15_0.

6.3.5.5.3. Connect with an SD Card Boot Image¶

1. Launch CCS and create a new target configuration (File->New->Target Configuration file) as shown in the images below.

Provide an appropriate name to the configuration. Select Spectrum digital XDS100 emulator and target as 66AK2G02.

In advanced settings, make sure that no GEL files are populated.

2. 66AK2G02 GP EVM contains boot switches to configure for “SD/MMC boot” mode. So configure the boot switches to “SD/MMC Boot” as described in the section “Setting Boot Switches.”

3. Connect an XDS100 Emulator to the XDS USB port of the GP EVM as shown in the section “Connecting Emulator.”

4. Launch CCS and create a new target configuration as discussed in the previous section “Configuring target configuration files”.

5. Launch the newly created target configuration.

6. K2G will boot with ARM master boot from the SD card so connect to the A15_0. There will be no output on the console when you connect to the core.

7. SD card boot image will typically load a secondary bootloader like u-boot that will put the DSP in reset so users will need to follow the instructions in the guide How to take the C66x DSP out of reset with Linux running on A15
