What is difference between OSTL v4.0.0 and OSTL v4.1.0

[GChin.1]

Hi Team,

There are two version of OSTL i.e. v4.0.0  STM32 MPU OpenSTLinux release note - v4.0.0 - stm32mpu-ecosystem-v4 and v4.1.0  STM32 MPU OpenSTLinux release note - v4.1.0 - stm32mpu-ecosystem-v4.  what is difference between them both are at 5.15.x kernel and using Kirkstone? 

Is OSTL v4.1.0/v4.1.1/v4.1.2 backward compatible with v4.0.0/v4.0.1/v4.0.2? @OlivierK 

 

Thank you.

Hi @GChin.1 ,

Release 4.1 is a maintenance release of the 4.0 ecosystem release using same Yocto (Kirkstone) and Kernel version (5.15) 

Differences are listed in STM32 MPU OpenSTLinux release note - v4.1.0 - stm32mpu-ecosystem-v4

Even if backward compatibility may exist, we always recommend using all components version from the same version, as validated by ST. 

Note that 4.x releases are no more supported by ST and so not recommended for new design. 

Please use the latest V6 

STM32 MPU ecosystem release note - stm32mpu
