Hi everyone.

On our STPC Vega evaluation board, we have a DiskOnChip connector. Earlier specs we had in hand speak of native DiskOnChip support, but this seems to have mysteriously disappeared in recent specs.

Does anyone have any information on this? Are DiskOnChips supported on the Vega? Or has this been abandonned?

In advance, thanks.

Hello,

DoC is not working well with the VEGA STPC and the STPC support team does not recommend to use it. That's why they disappear in the spec.

To complete the answer, Yes STPC VEGA are not supporting DOC but as an alternative more and more customers are using Compact flash through IDE BUS. It is an other solution to work with Files managed as an Hard disk with a removale Device.

Hello STpc support team,

Can you please explain what the actual problem is with the DiskOnChip on the VEGA evaluation board?

For example: Is it a noice problem, or a timing issue?

Can you think of a fix to implement in new designs?

Regards, Frank

Good comment Frankyboy! As the DOC needs nothing but a memory window on the ISA-bus, where is the problem? I'm not concerned about the DOC itself, but does that mean that there's a functionality limitation on the ISA-bus interface of the Vega?

After investigation our STPC VEGA support DiskOnChip. The incompatibility issue between M-System DOC and Rise CPU core can be resolved using the new firmware version 5.XX from M-system. So Millennium 8MB and upper and DOC2000 128MB and upper with the firmware 5.XX run well. Only DOC2000 from 16MB to 96MB are not supported. M- system advices people to better use Millenium than DOC 2000 in term of life cycle availability.
