The buffer is available here: /dev/iio:device0 Because the driver uses interrupts, you won’t get the speed you want. The driver has to be updated to use DMA if you want to use full speed. Reading from the buffer will reduce your CPU load compared to using LDR_PATH because this interface

To debug kernel modules with JTAG, you have to have a debugger which is kernel aware like Lauterbach. If you don’t want to use JTAG, then use printk or dev-dbg, dev-err, etc. You can also use ftrace, which requires you to build your own kernel and add support for the various ftrace features.
