Other Parts Discussed in Thread: Z-STACK, CC2538

I am using cc2538 RF Chip in my RF hardware module.

For programming it, I am using Bootloader using UART0 and pin PA7 (active High) to enable boot loader. 

Unable to program it through serial boot loader tool.

Please comment.

    Hi,

    It seems that you are using the ROM-based bootloader. Did you enable the backdoor? Please see http://www.ti.com/lit/ug/swru333a/swru333a.pdf

    Anyway, since you are using Serial Boot Tool, you should use the software bootloader instead, which is available as a project from the Z-Stack Home 1.2.2 installation, under Projects\zstack\Utilities\BootLoad

    Best regards,

    OD

    Hello,

    Thanks for your reply.

    1. We are using USB to TTL converter to program from UART0 Pins (Tool is Serial boot tool).

    2. Program from Projects\zstack\Utilities\BootLoad is been to dump into cc2538, but unsuccessful with "Device Command Response Timeout Operation State = Handshake ".

    3. Hardware connection's at Port A, Pin PA7 is Pulled up, PA0 & PA1 are connected to USB to TTL converter, rest Pins for Port A are NC.

    4. How to configure CCA and proceed further? 

    Thanks
