Override boot mode using SML CLI¶

A bit of background¶

AMD Zynq UltraScale+ MPSoC devices boot by using firmware from storage selected by boot mode pins. When accessing hardware remotely (as is the case in Smart Mission Lab), it’s possible to use SML CLI to override boot mode. Contrary to Override boot mode using JTAG this method set physical pins on Zynq UltraScale+ device.

Prerequisites¶

None

Steps¶

1. Log in to EGSE Host

   my-machine$ ssh customer@egse-my-egse.egse.vpn.sml.kplabs.space
   customer@egse-my-egse:~$
   

2. Set boot mode using SML CLI

   Antelope Leopard (PN1) Leopard (PN2)

   customer@egse-my-egse:~$ sml dpu boot-mode set jtag
   Setting boot mode to 0b0000 (jtag)...Success
   

   customer@egse-my-egse:~$ sml pn1 boot-mode set jtag
   Setting boot mode to 0b0000 (jtag)...Success
   

   customer@egse-my-egse:~$ sml pn2 boot-mode set jtag
   Setting boot mode to 0b0000 (jtag)...Success
   

3. Inspect currently set boot mode

   Antelope Leopard (PN1) Leopard (PN2)

   customer@egse-my-egse:~$ sml dpu boot-mode get
   Getting boot mode...0b0000 (jtag)
   

   customer@egse-my-egse:~$ sml pn1 boot-mode get
   Getting boot mode...0b0000 (jtag)
   

   customer@egse-my-egse:~$ sml pn2 boot-mode get
   Getting boot mode...0b0000 (jtag)
