XVF3610 firmware on XVF3800

Post by CorentinL »

Hello,

Can we run the firmware app_xvf3610_ua_v5_7_3 on a XVF3800 chip ?
As it seems to be made from the same XU316 chip, I would suppose it can work...

Kind regards,

Hey,

If by "3800 chip" you mean the 3800 dev board, then no. The pinout is very different.
But if you mean the actual chip, yes. 3610 and 3800 both run on the same chip package.

We already have evaluted both L71 and SQ66 dev kits.
We have also designed one board using 2 chips XU316-1024-QF60A-C24 and tried to run both firmware : "app_xvf3610_ua_v5_7_3" and "application_xvf3800_ua-io16-sqr".

The results are :
- app_xvf3610_ua_v5_7_3 is running fin on XU316-1024-QF60A-C24
- application_xvf3800_ua-io16-sqr is running partially (output sound is OK), but the input sound not. It seems there is some licensing needed for the AEC stuffs.
As seen from the datasheet, "Only XMOS parts marked with the V16A0VF3 product code are compatible with and licensed to be used with XVF3800 firmware."

In the next design, we want to replace the 2 chips XU316-1024-QF60A-C24 with 2 chips XVF3800-QF60B-C.

To be sure, you confirm that we will be able to run both firmware on XVF3800-QF60B-C ?

Also, which flash do you suggest as L71 and SQ66 have different flash size ? W25Q64JWSSIQ vs W25Q32JVSNIM

Thank you
