Help! Pro external Flash for K790/k800/k810

[eva]

I tried "mod" Professional Flash ( Connect to Fast Port of K790 )

If connect 1 resistor 4,7k from pin8 to pin9 of fast Port ===> Phone with External Flash ( as same as K750 ) ( External Flash MODE )

but I only received pulse signal from pin2 ( Display on Oscilloscope ) when Focus and Press .

SEE MY IMAGE :




and no signal from Pin7 ( Video/Strobe )

With K750 , Pin7 (Video/Strobe ) is a one shot ( Pulse ) when Use Flash and Press "shot"

---- I thing Problem with command in camdriver0.dat here :

// Property 14, Xenon flash support
//----------------------------------------------------

seq_set_prop_e_0 = $sb 00 $c9 08 #COM_EVENT(5a,00) $cl #COM_EVENT(5a,08) $cx;
seq_set_prop_e_1 = ; // No external flash

seq_set_prop_e_2 = $sb 02; // Auto
seq_set_prop_e_3 = $sb 03; // Auto, red-eye
seq_set_prop_e_4 = $sb 04 // Forced ON, for service menu and production tests
$c9 08 // R5 camera version?
#COM_EVENT(5a,83) // Forced xenon 0b10000011, slow sync at beginning
$cl
#COM_EVENT(51,00) // Sensor scene "Auto 00"
#COM_EVENT(5a,9b) // FLASH_MODE 0b10001011: Flash on, RER off, sync on beginning.
$cx;
