New product: MNT ZZ9000

[davec]

Have you tried sending an email to
support@mntre.com ?

I sent one the other day and at least got an acknowledgment (from a staff member).

Thanks -- I sent email to ask if a new release could be done. 1.13 distribution includes 4.19 zz9000ax.audio but there is a fix in the 4.20 version that is in the repository but not released:

"Fixed crash in the situation when interrupts are already coming in but playback was not started yet by ahi.device."

Separately, I have reported an issue ~2 years ago on when using DISPLAYCHAIN=NO related to SetGC() and SetSwitch() functions.

Attaching code snipets below in case somebody has knowledge how to fix:

https://source.mnt.re/amiga/zz9000-d...ref_type=heads

void SetGC(__REGA0(struct BoardInfo *b), __REGA1(struct ModeInfo *mode_info), __REGD0(BOOL border)) {

	MNTZZ9KRegs* registers = (MNTZZ9KRegs *)b->RegisterBase;

	uint16_t scale = 0;

	uint16_t w;

	uint16_t h;

	uint16_t colormode;



	b->ModeInfo = mode_info;

	b->Border = border;



	if (mode_info->Width < 320 || mode_info->Height < 200)

		return;



	colormode = rtg_to_mnt[b->RGBFormat];



	if (mode_info->Height >= 480 || mode_info->Width >= 640) {

		scale = 0;



		w = mode_info->Width;

		h = mode_info->Height;

	} else {

		// small doublescan modes are scaled 2x

		// and output as 640x480 wrapped in 800x600 sync

		scale = 3;



		w = 2 * mode_info->Width;

		h = 2 * mode_info->Height;

	}



	init_modeline(registers, w, h, colormode, scale);

}



int setswitch = -1;

UWORD SetSwitch(__REGA0(struct BoardInfo *b), __REGD0(UWORD enabled)) {

	MNTZZ9KRegs* registers = (MNTZZ9KRegs *)b->RegisterBase;



	if (enabled == 0) {

		// capture 24 bit amiga video to 0xe00000



		if (scandoubler_800x600) {

			// slightly adjusted centering

			zzwrite16(&registers->pan_ptr_hi, 0x00df);

			zzwrite16(&registers->pan_ptr_lo, 0xf2f8);

		} else {

			zzwrite16(&registers->pan_ptr_hi, 0x00e0);

			zzwrite16(&registers->pan_ptr_lo, 0x0000);

		}



		// firmware will detect that we are capturing and viewing the capture area

		// and switch to the appropriate video mode (VCAP_MODE)

		*(volatile uint16_t*)((uint32_t)registers + 0x1006) = 1; // capture mode

	} else {

		// rtg mode

		*(volatile uint16_t*)((uint32_t)registers + 0x1006) = 0; // capture mode



		SetGC(b, b->ModeInfo, b->Border);

	}



	return 1 - enabled;
