Hi Manorit, This commit added a possibly unintentional dependency on python 3.9+.
I ran into this while trying to build the soon-to-be-released 09.01.00.008. Build failure on ubuntu 20.04 which uses python 3.8: "binman: 'type' object is not subscriptable" This can be fixed by: diff --git a/tools/binman/etype/ti_secure.py b/tools/binman/etype/ti_secure.py index f80eb542c956..872c6d38ff46 100644 --- a/tools/binman/etype/ti_secure.py +++ b/tools/binman/etype/ti_secure.py @@ -16,7 +16,7 @@ class Firewall(): id: int region: int control : int - permissions: list[hex] + permissions: list start_address: str end_address: str > Hi Manorit, > > On Wed, 11 Oct 2023 at 23:02, Manorit Chawdhry <m-chawd...@ti.com> wrote: > > > > Hi Simon, > > > > On 11:54-20231011, Manorit Chawdhry wrote: > > > We can now firewall entities while loading them through our secure > > > entity TIFS, the required information should be present in the > > > certificate that is being parsed by TIFS. > > > > > > The following commit adds the support to enable the certificates to be > > > generated if the firewall configurations are present in the binman dtsi > > > nodes. > > > > > > Signed-off-by: Manorit Chawdhry <m-chawd...@ti.com> > > > --- > > [..] > > > tools/binman/btool/openssl.py | 16 +++++++- > > > tools/binman/etype/ti_secure.py | 90 > > > +++++++++++++++++++++++++++++++++++++++++ > > > tools/binman/etype/x509_cert.py | 3 +- > > > 3 files changed, 106 insertions(+), 3 deletions(-) > > > > > > from binman.entry import EntryArg > > > from binman.etype.x509_cert import Entry_x509_cert > > > +from dataclasses import dataclass > > > > What all python versions do we support in u-boot?
