TMS320F28069M: warning #10247-D: creating output section "ramfuncs" without a SECTIONS specification

Part Number: TMS320F28069M
Other Parts Discussed in Thread: C2000WARE

Hi,

Trying to modify the SPI loopback example

D:\ti\C2000Ware_1_00_04_00_Software\device_support\f2806x\examples\c28\spi_loopback_interrupts

by copying it as a new project throws me the above warning.

Attached my modified project as a zip file.

Wonder what causes the warning and how to resolve the same. Any suggestions ?

Thanks,

Manu

    The following change makes that warning go away.

    Multiple versions of F28069.cmd exists. The multiple versions are a bit confusing, IMO.

    Using the RAM lnk cmd file from

    C2000Ware_1_00_04_00_Software\device_support\f2806x\common\cmd

    did fix the issue. Strange though.

    Thanks,

    Manu

  • Glad you found a solution to your issue.

    We typically provide both a RAM-only version and a flash version. Since flash loads slower, it's sometimes nice to be able to use the RAM version for quick examples and experiments when memory size and volatility aren't an issue.
