Other Parts Discussed in Thread: CONTROLSUITE

I have downloaded the SPRUGO0B literature document for "TMS320x2803x Piccolo Boot ROM". But i am not able to download the source code for the same as the link mentioned in the document  is not working. Please do provide the appropriate link to download the same.

"www-s.ti.com/.../sprugo0.zip" --> Download error.

Regards,

Shriharsh

    Hello,

    The F2803x boot ROM source can be found in controlSUITE.
    Located within libs/utilities/boot_rom

    Best Regards

    Thanks for the reply. We will download and check the same in controlSUITE.

    I verified the TMS320F2802x document and links for the same are working. Wonder why only the link is not working for F2803x. It would have been quite handy to download the required source code instead of downloading the controlSUITE of 1.7GB.

    Hello Christopher,

    Thanks for the CAN bootloader. We are planning to remove the GetMode and force the BootROM to go for CAN upgrade state on every boot. CAN will wait for sometime instead of waiting for indefinite time and if no CAN messages are received from upgrade or wrong message is received then jump to FLASH_ENTRY point. Please confirm if this makes sense.

    Also if by chance if the flash BootROM which has some issues (software bug) then CAN we reflash the same using XDS100V2 again to restore the same with default factory ROM? This is just from perspective that JTAG works even if BootROM flashed is incorrect.

    The device boot ROM is unprogrammable, you will have to load a custom CAN bootloader into flash that you branch to and from there handle your flow to update/go to your loaded application. You can't overwrite the ROM code, so you can't reflash it.

    Refer to the flash kernel example for F2803x in controlsuite, which shows a custom SCI boot.

    Best Regards
