It is a part of the codification used in production of ST board, sorry if it is not clear. The ST product codification have several element - "Commercial Product Name" (CPN) : type of product board (DKX, EVX) - "Finished Good" or "Finish Good" (FG) : effective content of the product without chip STM32MP1 (LCD, Wifi, ?) - BOM: cost variant for same FG (for example, several provider of the same component) For example commercial product = STM32MP157C-EV1 Finished Good = EVA32MP157A1$AU1 Booth information are written on board. During production, this information is also save in OTP. And the stm32mp1 software can change its behavior based on this information. The FG information is introduced because on DK2 board (same product / same CPN) , we have a risk to manage 2 types of display in future production batch (no more availability of the current LCD => new FG for the same product with new display) > Best regards, > > Wolfgang Denk > Regards Patrick
