On a LCP2378.
I am using PWM to toggle control lines of a a/d and start a ssp (master) transfer at a 5us interval.
I've setup the DMA to move the (16bit) data to usbram.

Hi,
There are a lot of example code for SSP (not SPI), just for your
information.

Well, it was a hardware problem. I have mixed-up SSP0 pins (34, 37, 38) and SPI pins (60, 61, 62). This is my 1st design with LPC2000.
The LPC23XX user manual says that SSP c...

Try to prescale down a little bit the SSP port (and see what happens).
How long are your traces from the LPC to the SD card?

are unordered, giving a distortion for low signals.

Hi:
With MCLK=1.6MHz you are getting 5kSps.
With SCK=800Khz, you get a new byte every 10us, which might be too tight to read and process in the SPI0 Interrupt Service Routine...
