Hello
i have make a dvb-t ts graber with tuner and s3c2440
here have problem with parallel read
tuner i2c is set for signal,...but i have problem with read clk pin here speed is 5mhz ,i need fast GPIO on s3c2440 anyone can how i active this ?
you may get increase CPU speed by changing registers. Have a look at Samsung S3C2440 datasheet page 255 (7-21), the onboard quartz is a 12MHz one.
It should be possible to set clock speed at 532MHz with a 12MHz input quartz by setting MDIV to 0x7D, PDIV=1 and SDIV=1.
