Hi , 

I tried to do a Soft reset via memory writing from U-boot. 

What i have done on U-boot is.

 

Issue 0x1570204 , Core soft reset enable control register (CORESRENCR)
=> mw 1570204 ffffffff

Issue 0x1570130 , Core0 soft reset register (CORE0_SFT_RST)

=> mw 1570130 ffffffff

Then chip not reset.

I'm not sure it is correct register or soft reset sequence is correct or not. 

Thank you,

Nattapong

It is needed to check that the GIC interrupt mapping is performed correctly.

Please refer to the QorIQ LS1012A Reference Manual, 4.4.2 Core Soft Reset.
