Hello
Is i.mx 6 SoloX (MCIMX6X1AVO08AB) capable of starting with QSPI 2 - Nor - Flash boot even when USB-OTG1 and SD card are unmounted?
I wrote QuadSPI Configuration Parameters (512 B) to Nor-Flash offset value 0x400 connected to SS0 of QSPI2A1 using the J-TAG debugger, wrote u-boot-qspi2.Imx created with Yocto to offset value 0x1000 but it did not start.
BOOT_CFG[7:0] = 0x18 ([2:0]=000b,[3]=1b,[7:4]=0001b)
BOOT_CFG[15:8]=0x00
BOOT_MODE[1:0]=10b (Internal ROM Boot)
Thanks

I can not use MFG-Tool because my i.mx6sx custom board does not have USB-OTG 1 and SD installed.

Hi Yuri
I was using the oscilloscope to monitor SS0 of QSPI2A1 when i.MX6SoloX was started, but it never changed to low.

Hello, Hirokata !
please check pin connection, using Table 8-27 (QSPI IOMUX pin configuration)
of the i.MX6SX RM (Rev. 1, 6/2016). Also, You may send me circuit diagram of Your design
for verifying - via request.
Regards,
Yuri.
Thanks, Yuri
Sorry, I can not send the circuit diagram to you because of the confidentiality obligation.
I tried tracing from the reset vector with the JTAG debugger.
At the address 0x0000286C of the Internal ROM, the CMP instruction is always true, so an infinite loop has been established with 0x0000286A.
What is this judgment?
Does it fail with secure boot?
Is i.MX6 SoloX able to boot without writing the program with MFG-Tool?
Can not I start up if I write directly to Flash ROM?
Regards,
Hirokata.
Thank you, Yuri.
How can I do it?
Should I issue a question in the JTAG debugger as a new request ?
Hello,
As for the new request :
I am going to send You boot utility to have more information about the issue.
Regards,
Yuri.
