Dear All,
This is regarding imax6 processor based custom hardware design.
1)----------------------------------------------------------------------------------------------------------------------------------------------
I tried to run DDR calibration with v.2.7 and v.2.6 but it still get the following error when I click Download on GUI :
"ERROR: Write dcd failed."
But when I comment the following line of the script it run correctly.
//setmem /32 0x020c406c = 0xffffffff
What is the reason for this ?
One of my another custom hardware design which has same design like above I needed to comment following line to load DDR Calibration Script.
//setmem /32 0x020c4080 = 0xffffffff
What is the reason for this random issue ?
2)-----------------------------------------------------------------------------------------------------------------------------------
I tried to do this memory calibration using DDR_STRESS_TESTER V1.0.2 as well. Then It occurred following problem.
MX6DQ opened.
HAB_TYPE: DEVELOP
rom_write: reading HAB ack failed 0x00000000
ROM Write failed, addr: 0x020c406c
Write dcd failed.
Is this related to (HAB) High Assurance Boot component ? Some issue with the processor ?
3)----------------------------------------------------------------------------------------------------------------------------------
But
setmem /32 0x020c406c = 0xffffffff
setmem /32 0x020c4080 = 0xffffffff
Above values are in valid address range. And some of my boards could run this script without commenting it. Why is that ? Is this some thing related to iMAX6 manufacturing ? Will they do this kind of restrictions for different batch of productions ?
Regards,
Peter
