Hi OMAP Team,

There are lots of USB OTG posts on the community. Is OMAPL137 USB OTG working under MontaVista Linux Prof. 5.0 version? Please advise.

    MontaVista Linux PSP for OMAP-L137 includes,

    • Demonstration version of MontaVista (MV) Linux Pro 5.0 (Kernel Version 2.6.18) ported for OMAP-L137 EVM. The kernel is compiled with MV Pro 5.0 ToolChain based on GCC 4.2.0.
    • U-Boot version 1.3.3 ported for OMAP-L137 EVM. The U-Boot is compiled with MV Pro 5.0 ToolChain based on GCC 4.2.0.
    • User Boot Loader (UBL). This is the primary boot software which copies U-Boot to SDRAM and starts it. This software requires CCStudio 3.3 for building.
    • SPI and NAND flash writers. These are Code Composer Studio(CCStudio) based utilities. CCStudio v3.3 is supported on the OMAP-L137 EVM. (See important note on NAND flash here)

    To answer your question, in the LSP ( Linux support package) provided, only the configuration for USB 2.0 ( as host or gadget ) and USB 1.1 are available. There is no proof of USB OTG configuration on Monta vista Linux pro 5.0 .

    But, omapL137 + USB OTG + Davinci PSP has been verified and validated.
