Virtex-5 SPI Programming Compatibility

[ltuscany]

Is there a published list of compatible SPI flash devices for programming Virtex-5 devices (like the list in UG-908 for 7-series devices)?

Specifically, we are using a XC5VLX30T-1-FF665 and are targeting a Macronix MX25V1635F to replace the old flash which has reached its end of life.

Thank you.

Hi @ltuscany ,

Yes, their is a list of flashes supported for Virtex 5 Devices. Please refer this Link .

@ddn,

I followed that link to these answer records, AR# 68677 and AR# 68678, can you provide similar guidance for the MX25V1635F or must we reach out to Macronix?

Thanks.

Hi @ltuscany ,

Apart from the link i gave you in my previous post, there is no other special supported case for Virtex 5 devices.

You need to choose Flash from  supported list mentioned in the link. 

Workaround : Note, this is a workaround and not a solution.

If you still want to use some unsupported flash, please ensure that command set of unsupported flash matches with the command set of one of the supported flash listed in that link. Then before programming the flash you need to set the environmental variable, XIL_IMPACT_SKIPIDCODECHECK=1
This variable instructs the iMPACT tool to bypass the ID check, allowing the programming operation to proceed.
