XHRA-2HPA number of max. intructions in events

Post by jul »

Hi all,

unfortunately I could not find any documentation about how many instructions can be executed in the events, such as EVT_SYS_INIT = [] or EVT_USB_CONNECT = [], ...

Is there an upper limit? I tried to fix my problems (https://www.xcore.com/forum/viewtopic.p ... 268#p23268) with a temporary workaround, but sometimes the XHRA-2HPA does not make anything, also the image on the flash (created by the xConfigurator) is verified. Maybe this behavior indicates, that the number of executions is exceeded?!

Thank you!

Valid question. In general USB requests should be dealt with < 1 second (sample rate change etc) The init and connect events are likely to be more sensitive. I will have to look into this.

I am not sure if this helps, but XHRA cannot support more than 2048 bytes in its configuration flash.

Cheers,

Thank you Henk. Good to know.
In this case my workaround is unconvertible, anyway.
But I wonder, that I could create a configuration with more than 2048 bytes and there was neither an error nor a warning?!
