    Bernie Thompson TI
    Unfortunately almost all of the collateral TI provides for the OMAP3 will be based on some high level OS like Linux or Windows CE, the device is complex to the point that it is not practical to try to offer a software solution with no OS out of the box, much like if you were to buy a PC it would not...

    I don't have a lot of choice since the board will not be equipped with an EEPROM. I'm not willing to develop my own driver since the TI EMAC driver should be sufficent for me apart from the fact that it now gets it's MAC address via i2c. What is the reason you think I should consider...

    I'm currently developing on the OMAP L-137 EVM. The product I'm developing for will have the same Ethernet physical as the EVM but no i2c configuration EEPROM. The Ethernet driver on the EVM is the davinci_emac.c developed by Ti. I've disabled i2c in the Kernel configuration and now the driver...

  • Forum Post: Re: OMAP-L138 EVM SPI Flash read performance and boot time

    Stephen Turner
    We have scoped the SPI clock and have discovered that each SPI byte read takes ~160ns (correct for 50MHz SPI clock). Then there is a ~1us delay between the next SPI read. SO the question is whats going on here?. Is the mDDR not setup correctly?. Is it the fact that (we believe) the L2 cache is not enabled...

    Delio Brignoli
    Hello, I am looking at the reducing boot time for the OMAP-L138 SoM. The current bottleneck is the SPI Flash read speed in U-Boot of about 0.6 Mb/s. U-Boot sets the SPI clock at 50MHz, so I would expect a faster transfer rate. Is there a reason for keeping the transfer rate low or is it simply lack...

    Hello. We are starting a development over OMAP-L138 . The hardware will boot from SPI-Flash, and will use U-Boot as bootloader and Linux as OS.

    Since AIS is capable of initializing external memory and other CPU peripherals, i wonder if it is possible to boot directly from a AIS signed kernel image.
