Original question:

CCS/EVMK2H: How to load the Linux operating system into flash

CCS/EVMK2H: ARM-master or C66x-master boot-mode is used?

Alexandr Perepechay
Intellectual 640 points
Part Number: EVMK2H


Tool/software: Code Composer Studio

What boot-mode is used in EVMK2H? ARM-master or C66x-master?

If ARM-master mode is used and If I load the operating system Linux as is described in "Linux Getting Started Guide"

software-dl.ti.com/.../Overview_Getting_Started_Guide.html

 then will the kernels c66x be involved in work? 

Can I work with c66x under the control of the Linux system?

Second question.

In EVMK2H There is provided "0010:NOR SPI BOOT" mode (or No Boot/JTAG).

And if I load the operating system Linux as described in "Linux Getting Started Guide" is it loaded only in NOR whithout using NAND?

(NOR-flash is small !)

And one more.

Where BMC code of EVMK2H is located? In flash (NOR or NAND)?

If this code will be corrupted how can I restore it?

Regards, Alexander.

    Hi,

    When you install linux ARM is the master core that runs the operating system. Yes you can still have the DSP cores funning RTOS applications.

    In EVMK2H There is provided "0010:NOR SPI BOOT" mode (or No Boot/JTAG).

    And if I load the operating system Linux as described in "Linux Getting Started Guide" is it loaded only in NOR whithout using NAND?

    (NOR-flash is small !)


    No, just the bootloader is flashed on the NOR flash. The filesystem & the kernel are on the NAND.

    Where BMC code of EVMK2H is located? In flash (NOR or NAND)?

    If this code will be corrupted how can I restore it?


    The BMC is located on a separate EEPROM memory.

    Here is the steps you need to take in order to update the BMC firmware:

    The Firmware is available on the vendor's website:
