Dear Sir or Madam,
[Q1]
Refer to Table 8-2. Boot eFUSE Descriptions in MCIMX6DQRM(Rev.2).
There is below description.
------
BT_FREQ (BOOT_CFG3[2])
0 - ARM - 792 MHz, DDR - 396 MHz, AXI -264 MHz
1 - ARM - 396 MHz, DDR - 352 MHz, AXI -176 MHz
------
Next, refer to Table 5-4. EIM Boot Fusemap in RM(Rev.2).
It was "Boot Frequencies (ARM/DDR) 0 - 792 /528 MHz"
Which description is right?
[Q2]
freescale has 2 type of i.MX6DQ auto product, 1GHz or 852MHz grade
Could you tell me a selectable BOOT frequency combination in BOOT_CFG3[2](BOOT Frequency Selection)?
(ARM / DDR / AXI)
Best Regards,
Keita
Solved! Go to Solution.
1.
This is a misprint in our i.MX6 Reference Manual :
it is mentioned BOOT Frequency as “ARM - 792 MHz, DDR - 396 MHz”,
but it should be ARM - 792 MHz, DDR - 528 MHz”.
2.
Both BOOT Frequency selection options are acceptable for any of i.MX6 DQ auto
qualified parts (1 GHz and 852 MGz).
Have a great day,
Yuri

Hi Yuri,
Thank you for your prompt reply!
OK. I understood ARM - 792 MHz, DDR - 528 MHz are correct at boot frequency.
