Do you have a source on the chips being in hand but defective?
As known by OEM producers, several large batches of BE200 had problems with
popping chips affecting whole boards due to the misoperation from the packaging
company. It hindered afterwards chip sales and delayed the starting time of
Tube/Prisma sales. Later supply of BE200 has no such problem and filtering process
on old BE200 is also underway.
Sounds like this happened a while ago.
