@kuleszdl I'm not sure if it's possible because that particular firmware is signed by NXP. Maybe that can be cracked/circumvented, I don't know. The ISA of the blob should be Xtensa.
@mntmn Thank you! What is the size of this blob? And does it need to be loaded with root privileges to enable the output?
@kuleszdl the firmware is 103kB in size, but it is mostly empty. zipped it is 31kB big. it can be loaded together with u-boot or later by the HDMI kernel module.
@kuleszdl it does not run on the ARM but inside of the HDMI controller on some tiny embedded MCU.
@kuleszdl this is what the end of the file looks like, where you can see the iMX_CA@nxp.com mentioned
@kuleszdl this is what a disassembly in Cutter looks like
@kuleszdl Cutter can make call graphs of it
