My customer has recently gone into production with the CC1110 for range of RF ID products and have come across some odd issues.
One of the issues in a number of case was the last page of flash ROM becoming erased. Their configuration goes into this page so devices were failing due to lost configuration. They coded around this by having another copy of the configuration in the 2nd and 3rd last page which the code will check if it finds an empty configuration.
But the latest issue we have come across is a device where the first page of flash ROM has erased itself. As this contains the actually application program the code cannot deal with this issue.
They have gone through their code top to bottom, check it and rechecked it but can find no where that we could ‘accidentally’ erase a page of flash.
