otfdec in stm32mp257

jgd · ‎2026-04-01

Hello ST community. I am trying to understand the support the otfdec https://wiki.st.com/stm32mpu/wiki/OTFDEC_internal_peripheral internal device has or will have in the OpenSTLinux. Can anyone suggest reading material on supporting the otfdec for mp2?

Hello @jgd ,
Today there is no plan to bring the software support for this IP in OpenSTLinux due to lack of use cases.

Kind regards,
Erwan.

Hi @jgd ,
My comment targeted A35 (Linux) side, but we have some HAL driver for M33 baremetal application in the CubeFWPackage.

Kind regards,

Thanks @Erwan SZYMANSKI . Is there any reading material on the OSPI and OTFDEC for M33 in mp2? The following is the only reference I have found:
