Hi,
From: Patrick DELAUNAY patrick.delaunay@st.com Sent: mardi 24 mars 2020 14:36
Update the command stboard to support the updated coding of OTP 59 with finished good.
The ST product codification have several element
- "Commercial Product Name" (CPN): type of product board (DKX, EVX) associated to the board ID "MBxxxx"
- "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 and these information is also saved in OTP59:
bit [31:16] (hex) => Board id, MBxxxx bit [15:12] (dec) => Variant CPN (1....15) bit [11:8] (dec) => Revision board (index with A = 1, Z = 26) bit [7:4] (dec) => Variant FG : finished good (NEW) bit [3:0] (dec) => BOM (01, .... 255)
The updated command is: stboard [-y] <Board> <VarCPN> <Revision> <VarFG> <BOM>
And the displayed STMicroelectronics board identification is: Board: MB<Board> Var<VarCPN>.<VarFG> Rev.<Revision>-<BOM>
