Boot DM37xx omap3evm from USB port not working

Other Parts Discussed in Thread: FLASHTOOL

Hi,

I am trying to boot DM37xx omap3evm kit from USB port

I have set the sysboot[5:0] pins through SW4 dip switches to set the first boot from USB port and and second from NAND.

Steps followed:

Connected USB(OTG) port on EVM with Ubuntu PC.

On Ubuntu I ran a Linux USB utility(found on beagleboard forum) for sending u-boot through USB.

Then I powered on the EVM kit.

I was not able to transfer any image through USB.

Experts please advice.

 

By the way on UART3 I could transfer and run a test application successfully, but we have use case where we need to transfer images through USB only.

 

Thanks in advance,

Pawan

    Hi,

    We have tried with Windows Flashtool 1.6 utility also.

    When we connect the DM37xx EVM kit to windows PC through USB, we get an error "Driver installation not successful". Then if we try to flash the xloader image using flashtool 1.6 we get below output:

    ***********************************************

    ¯ Looking for device (omap usb)

    ¯ Please turn on device

    ¯ Waiting for device (omap usb)

    ***********************************************

    Flashtool is not able to detect the EVM kit.

     

    Our sysboot dip switches were set to 0b101111(sysboot:5:0). Boot sequence set is USB->UART3->MMC->NAND.

     

    We have tried with UART3 also. We could erase the nand sectors using flashtool 1.6 on UART.

     

    Thanks,

    Pawan

    Hi,

    The problem has been resolved.

    Windows was not able to find the driver at Flashtool installation folder. After manually installing the windows driver flashtool is able to write to nand successfully.

     

    Thanks,
