After a lot of troubleshooting on my custom design based on the BF504 processor , I found out that anomaly 05000490 and also 05000469 are giving me headaches.
Basically the DSP sometimes fails to do a SPI boot correctly or sometimes it will latch incorrect PLL values so my clock timing will be wrong.
Sometimes everything goes fine, so I keep restarting until the boot proces is correct.
I see that in revsion 0.1 these problems are solved. My question is , did someone had the same troubles and , because of this , is using revision 0.1 right now ??
If yes, can you confirm that these problems indeed do not occur anymore ??
I am still prototyping, so I can still change the processor instead of doing all the workarounds.
Another question: where can I find BF504 revision 0.1 for purchasing ??
Digikey still have 0.0 in stock , and Farnell / Newark cannot provide me with this information about revisions.
