Subject: load BL31 on imx8mm and imx8mq
Date: Wed, 26 Jun 2019 08:46:56 +0000 [thread overview]
Message-ID: <24b0cc8b-93b2-ccf8-9b9d-1d618584958e@data-modul.com> (raw)
Hello everyone,
On the process of bring-up imx8mm board, I am at the point that load bl31 and
jump to ATF.Upon exit from ATF's initialization routine, the execution level
should be EL2.
My question is about imx8mq_atf_load_bl31 function.
After copy BL31 into OCRAM address, the function sets up the sp_el2 to
"MX8MQ_ATF_BL33_BASE_ADDR - 16".
Can anyone explain me why this address? Because I am using the same address for
imx8mm and it seems Barebox does not return to this point.
Best,
Reyhaneh
