The NXP intermediate certificate is signed by a NXP root certificate. To be able to verify
the validity of the NXP intermediate certificate you need also to download the NXP root
certificate.
The NXP root certificate can be downloaded via the following link:
ca.nxp.com/CA/getCA?caid=63709315050010
We can use again the Linux command
wegt
to download the certificate:
wget https://www.gp-ca.nxp.com/CA/getCA?caid=63709315050010 -O
nxp_a5000_root_ca.crt
Figure 27. Download the NXP root certificate
Finally we also convert the NXP root certificate into a PEM formatted certification file
(
nxp_a5000_root_ca.pem
).
openssl x509 -in nxp_a5000_root_ca.crt -inform der -out
nxp_a5000_root_ca.pem -outform pem
cat nxp_a5000_root_ca.pem
