Tf534 problem with IDE speed

[terriblefire]

yes i have fast drive but after connect this INT0 keyboard stop working
in Amiga Test Kit no even one button work
in WB Classic on WDHLoad i cant finish demo or game only reset working
can anybody give me some advice please

I checked (because its been a while). You shouldnt actually need this INT2 cable on the TF534. Its got the man in the middle interrupt hack like the TF536.

My guess is you have something holding INT2 down forever on your board if this causes the keyboard to stop working. I'd almost bet that if you connected the A500 INT2 to ground you'd see the same behaviour. Pretty sure there is a fault somewhere on your board that you'll need to track down.

when i connect INT2 to GND keyboard start working
but again start problem with speed HD
responsible for communication IDE is 74AC16245 ?
Maybe this lad is bad?
i bought on alliexpres this one maybe is fake

I'm using this IC: https://www.digikey.no/product-detail/e ... ND/7033455

No problems with IDE and I don't have Int2 connected to anything. A500 Rev 5. I get 1,5-1,9 MB/s with MMU enabled. I think the seek time is more important than the read speed for an Amiga 500. An SDCard is much quicker than a Compact Flash card for me even though the benchmarked speed in SYSInfo is roughly the same.

sorry when i connect INT2 to GND transfer on IDE go down to 5kb/s

No this isolates the fast 32 bit bus from the 16 bit bus on the amiga. It also helps the CPU drive data to the Amiga.

You have an issue with your interrupt path. At this stage you need to start diagnosing.

What firmware are you using.

Does DiagROM pass all the IRQ tests?

look at the schematics and whats involved in interrupts. I.e. IPL0-2 .. are any shorted together?

Do you have a short on the IDEINT resistor? is it the right value etc.

I cant help you with this board right now i'm nowhere near home.

IRQ Fail
Firmware is tf534R2c
Board PCB as well is r2c

Firmwares have a date. What date is your firmware. Also check you don’t have an issue without the 534 in place. My bet is two IPL lines shorted.

I check this resistor I have 2k2
Without tf534 amiga pass test on IRQ
Firmware what I have is

What date is on the folder you unzipped that from?
