error in compilation optee with Yocto for imx8mm

Hello,

I am trying doing what suggested by the webpage linked on the document :

 https://www.nxp.com.cn/docs/en/application-note/AN12632.pdf

 it is this page : 

https://source.codeaurora.org/external/imxsupport/imx_sec_apps/tree/enhanced-openssl/README.md

it is everything OK until I compile with bitbake :

bitbake -f -c compile optee-os-imx

bitbake optee-os-imx

I get error in compilation of recipe "Bison".

What should I do in this case ? I tried looking online for the error and applying a patch for it but it then gave me other error.

I was hoping that following those instructions would have led me quickly to have optee for imx8mm but it is not at the moment.

Is there an update I can use ?

 

thank you
