something i have not tried,

I have however had luck with:

• Loading to ROM in that area e.g. UDG chars
• Just setting it to RAM, and software that loads in 16-32k relocates itself to area 8-16k

yes i can load data into the Flash rom and access it ok.

when set to ram every byte reads as 255 , writting to it has no effect and it still returns 255 when read

Rumors says that the bug is found and is fixed in the next firmware version. No indication when that will be though.

I have however had trouble that the area shifts from RAM to ROM automatically. Sometimes I have to set it for RAM, and try again. If it fails the set to RAM again and try again. Sometimes even if the configuration screen lists this area as RAM, I change it to ROM and back to RAM, to be sure it is selected as RAM.

Has anyone tried to have ZXblast and ZXpand connected at the same time. Can they coexist?

Hi there, how are you? I'm one of those lucky users that bought a ZXBlast a couple of years ago

Since that time, I've been trying to figure out how I might upgrade the CPLD to the final version. Is there any way to do that without the need of a CPLD shipment? I've seen that the board has a USB Program pinout/socket, that might work with a JTAG/Based Programmer (with the Altera USB Blaster). I don't have experience working in this manner (I just have the typical makeshift EEPROM Programmer for other purposes).

If further information might be provided, it could be a great time to upgrade the User Manual with the procedure, if possible. I will also try to reach PokeMon for further instructions. Thanks to everyone for your patience!

A new version of ZXblast is planned during this (maybe cold) winter.
Winter is coming.

Given the 18.9mm of rain (in the last 24 hours) and the electrical/lightening storm that happened in my area last night, I would say winter is already here

Is that a new hw version, upgraded hw (cpld) or new fw?

It is planned to upgrade hardware (CPLD) and software.

Sounds good, so all of us with the "old" zxblast will be able to upgrade somehow? Can't wait to see your progress regardless.

Thank you PokeMon, I will wait for the next release: I guess that to jump from v1.0 to v1.[1+] will require to rely on a shipment of a new batch of EEPROMs/CPLD. I will stay put, winter comes!
