I've been trying to update a Thinkware F750 without much luck. In doing so, I noticed it follows the normal Ambarella setup so thought I could force an update using ambsh/autoexec.ash. I wanted to take a backup first using:
Code:
firmfl gen 8 bst bld hal pri sec rom dsp lnx backup.bin
However it times-out and the camera restarts before finishing. I've tried backing up sections one at a time, and it's definitely a timeout (pri rom and lnx are all too big to be backed up even on their own without causing a timeout).

Since it times-out backing up, I'm concerned it would do the same when writing an update (and brick the device).

Does anyone know if there are any ambsh commands to increase/disable this timeout?

FWIW, the ambsh commands available are:
Code:
supported built-in commands:
    addr2func    bp        cardmgr        cat
    cd        chmod        config        cp
    cpu        date        deletedir    dmesg
    dramcfg        drives        dsputil        echo
    eeprom        eval        false        ffuc
    format        hal        help        history
    hotboot        ioerr        jobs        kill
    ls        md5        mesg        mkboot
    mkdir        morph        mv        flashdb
    nice        poweroff    pref        ps
    pwd        ramdisk        readb        readl
    readw        reboot        reset        resume
    rm        rmdir        savebin        sleep
    suspend        sysmon        t        test
    time        touch        trap        true

Some interesting ones to play with in there!
