Hello. Could someone clarify for me where this message is coming from and how can I fix it?
stm32_etzpc bus@5c007000: rng@54003000 not allowed on bus (-13)
Is it OP-TEE or U-Boot miss-configuration?
I'm trying to patch openstlinux-6.6 OP-TEE and U-Boot for the STM32MP157C Odyssey based on the https://github.com/Seeed-Studio/meta-st-odyssey
