This interrupt scheme is where my problem occurs.When using the driver alone, I don't get any interrupts.It looks that isis bootcode in maxiinit (SAM9707) is different than generic bootcode (9407) in ALSA SAM driver (SAM9407 vs. SAM9707 differences perhaps?). I got bootcode from sam9407-1.0.0 package (by Gerd Rausch).
So I thought of the following: why not load the firmware from userspace, and use my new driver in stead of the es1968 one. So I loaded the ISIS driver, then started the maxiinit app, and to my surprise the driver started to catch the SAM interrupts. So now my situation is:
Scheme 1: loading snd-isis, then trying bootload through HWDEP interface => failure (no interrupt, meaning timeout)
scheme 2: loading snd-isis, run maxiinit, then trying bootload through HWDEP interface => success (interrupts are generated, all ok)
the strange thing is that both maxiinit, and the HWDEP ioctl 'bootload' are doing exactly the same.

Could you try to boot SAM with a bootcode from maxiinit driver?
Perhaps a delay value in sam_ucode.c is too low, but if you received correct checksum on microcode start, this is not the cause.
