I have some CC9P9215 which are not booting. The orange and green LED are blinking alternately. In the manuals the only part where the LEDs are mentioned is in the Hardware reference: […] During startup, LE1 will flash a repeating blink pattern for a major syst em failure; for example, a processor exception or power on self test failure[…] Is there a table where i can see what blink pattern means which failure? ---

There are different blink patterns for different portions of the code. Below is a general table for Netos, but if it crashes in bootloader, then it’s probably simpli indicates that image is corrupt, which is most likely what the customer is seeing. Those patterns are only usefull if you know exactly what part of code is failing. All this inof is in API reference guide. I’ve copied it below but it’s poorly formated when pasted here, so please look it up there instead. Netos gives you a main code with red LED and subcode with green LED: LED Error Blink Codes Category: Error and Exception Handlers Error code for customizeErrorHandler().
