- Subject: [ECOS] When to enable the IE bit of MIPS status register in eCos?
Hi all,
I am quite new in the eCos world.
I tried to port eCos to my MIPS platform, but i got a question.
In what stage will the eCos kernel enable the IE bit (global interrupt
enable) of the STATUS register?
Or i have to do it in cyg_user_start() function by myself?
Will it make the system unstable if i enable the IE bit early in the
hal_platform_init() function?
Any hints are appreciated.
Thanks,
KJ
