[8 Bit Dreams]

Wow! Not cheap..
Yeah...4-Layers, big CPLD, also RAM isn't expensive..
I need to figure out how donate works, have tried on last stream, but got message it isn't working in my country...

No donations required. It was just for reference.

Customs fees were 23 quid for example. This is why I try and use what I already have lying around for parts

HI Stephen, glad to meet you again here .

Ok just realized the latest TF530 firmware doesn't work properly at 25 mhz, no issues whatsoever at 33 Mhz and up however.

OK. New beta available. give it a whirl.

https://github.com/terriblefire/terribl ... 7_beta.zip

Can I ask you a little favor? Can you please put 0/1 (JTAG chain ID) in the JED file name so that I don't even to look up in the docs every time to find out what file goes on which chip?

Anyway, in the end I didn't buy the programmer, I macgyver'ed my own with xc3sprog and a STM32 Black Pill. That makes up a very cheap programmer, cheaper than a RasPi. If anybody is interested I can clean it up and release it.

Can’t you just create flashramcpld.sh and flashbuscpld.sh scripts?

I don’t know how to do what you ask automatically and I create the jed files with a make file that auto packages everything. Hand editing 7 jeds per release (and counting) isn’t going to happen.

[SukkoPera]

OK, no worries then .

DHL just emailed to say they’re delivering today. First look at the boards tonight

[SukkoPera]

I have a few questions:

Since the CF/IDE adapter I use supports powering through pin 20 of the IDE connector, and since it is unconnected on the TF530, is it OK if i solder a wire from some 5V pin to pin 20?

Would you also keep this in mind for your newer boards? Maybe connect it through a jumper so that it can be disabled.


Question #2: Can I connect an IDE activity LED somehow? Another thing to consider for future boards.

Question #3: What is the BYPASS jumper for?

Thanks .

All my new boards are 44pin ide with power supplied.

I always just use CF adaptors with LED connectors.

Question #3: What is the BYPASS jumper for?

Thanks .

Its for programming the bus CPLD without the RAM CPLD soldered in..

Oh ok, but so do you see anything wrong if I solder a wire to pin 20 on the 530?

That would be fine.. but its probably less messy to power it from the PWR header directly
