Work with Alcor

before all take a look that

this is last Schematic from alcor

channel 2 is not used why? i dont know
but also tagaraz say in usbdev alcor 2014 not support l74 dual channel mode

may be new nand have a problem with dual channel

may be 1 time ask from nat27


i have 2 " K9LCG08U0A" and orginal brand and i know if i used in 2250 speed is a trash|! w=13 r=17

2251 famly in read speed kill my self i used toggle memory in 2267 but read speed is =23

so i dont like used my gook nand memory in this device

and i havent 2238 ,and i dont trust it1167b speed some time 30 ~25|~18

Finaly i will used new controller and leave 6987 or 6990

i used old pcb

i think new pcb is not support dual channel

just interleaved mode

so i used 6987 pcb
i uploaded big to people see good

used AlcorMP_v13.02.05.00

speed optimize
fast scan 1
and result is
before this i made

6986+micron l63 2ce /*2 channel =r 30 w18
6987+micron l63 2ce /*2 channel =r 30 w18
ite1167+micron l74/*2channel r=30 w=16

3257ena +toshiba toggle mlc 2ce interleaved=r34 w=19

2233+toshiba 43nm mlc 2ce */2channel =r=30 w=17

but never spped more than 20mb in usb 2

jet flash v600 also 6989n + spansion l74

look dear frinds spansion also used micron id but is cheaper and speed is lower

if u open the cover «fcg...»
so in jet flash v600 write speed is 16~18
