Re: TF534 Amiga Test Kit exception errors

I've never understood why people cheap out on those CPLDs. You will drive yourself insane if it has one IOB dead.

Re: TF534 Amiga Test Kit exception errors

The test kit errors are the state of the machine when it crashed. Looks like a bus error occured.

So my question is what address I can use for this purpose?
It will need to be in the 24 bit address range as the plain CD32 would need to access it too.

The area BAOOOO-$BDFFFE is marked as reserved.... you could use one of those addresses.

Re: DiagROM works fine with TF536 in A2000, but no boot with kickstart, not even to early startup control

First.. are you on the A2000 firmware? Then In DiagROM... 1. have the CIA tests passed 2. do the IRQ tests passed 3. Do graphics tests pass. 4. does a slow memory test pass for the range 0x40000000 - 0x44000000 5. If you type ABCDEF into the memory editor at address 0x40000000 and hit R does it pers...

There is still SDMMC controller on the chip, which could be used instead of usb sticks, or crude way of just providing floppy port to attach external gotek?
Yeah we could reroute the SPI interface between the CPLD and ARM to an SD card slot... since the spi port is unused?
