TMS320F280023: Device cannot boot to flash

TMS320F280023: Live Firmware Upload

Part Number: TMS320F280023
Other Parts Discussed in Thread: C2000WARE

Dear Expert

Could you provide some guidance file about F280023's live firmware upload.

At present, we have two main problems as follows:

1) How to write fixed information to a certain address of Flash, for example, 0x00800000, the next 32 bytes are written to 0x55.

2) How to set the boot item, for example, from the boot segment to the app segment? At present, 0023 has no fixed boot address, right?What's the difference with 034?

    Hello,

    I am not sure I understand your questions correctly, hence seeking clarification.

    1. What do you mean by 0x55?

    2. What do you mean by 0023? and 034? Are you referring to the device? F280023? F28034?

    We have an example Live Firmware Update example on F28002x. It is not yet released in C2000Ware, but available as MySecureSoftware. Would you be interested in accessing this MSS?

    Thanks,

    Sira
