    Hi, i have just bought the lh7a400 starter kit and the 3.5" lcd,

    I also have the ashling Opella JTAG( and it works fine...)

    I have a few problems i can't seem to solve..

    1) Is there a usb lib? if so where is it!!!
    2) Is there an ethernet lib? same...
    3) can the CF be run in IDE mode... i would like to connect a harddisk, if not what other options do i have?

    Final product needs...
    LCD 3.5" +touchscreen
    32MB sdram
    MMC in MMC mode
    SPI device
    IDE hardisk/cdrom using level converters...
    USB
    32MB FLASH
    serial EEPROM
    some buttons



    4) My final product will need to be very small, so the cpld won't be needed, how can i disable it for development? what will this affect?
    Is it possible to use 32mb stratflash without buffering?
    Is it possible to use the CF without buffering?
    Is it posibble to swap between an SPI device and the MMC (from what i can figure out there is only one CS line for the SPI??)

    5) Is there a FAT16/32 lib for this board?

    6) the windows ce serial number given to me by you does not work!!!
    It has been tried on 3 machines, and typed in by 3 people!!! any ideas..
    (i don't need wince but would like to have a look)

    7) i downloaded the pre-build CE image from your site, copied it on to the CF, with the autoexec.bat, along with setting the eeprom, and can't get it to boot... is there an example autoexec.bat somewhere?

    eeprom set using:
    echo "LOLOmount fatfs /cf ; source /cf/AUTOEXEC.BAT ; exit " /dev/serial_eeprom

    autoexec.bat ( i got of here i think)
    load bin /cf/NK.BIN; exec dbg_serial:A400_UART:dbg_enet:91C111:dbg_enet_base:0x70000000:rtc:rtc_a400_int:share_eth:1

    when lolo boots, it displays the 'echoed' cmd but does nothing... after a short wait it comes up with the lolo menu....


    Also do you know wether IAR will be supporting this CHIP?


    BTW, i too would like to see a SPI lib....

    I use GreenHills Multi2000 V3.6.1




    Many thanks in advance....
