How to burn U-boot using JTAG for IMX6Q

vijanakaush — Tue, 21 Jan 2020 10:34:00 GMT

Hi,

We've design a custom board based on IMX6Q. Currently we are using a SD card to burn U-boot bootloader. Is there any way to burn U-boot boot loader using J-Link Segger JTAG debugger without using SD card? #uboot #jtag

Hi Vijana Maparathna

Please refer the link for loading u-boot using j-link and make the following changes in imx6q-2gb-oocd-0.8.0.cfg file

1) Comment this line #ft2232_device_desc "VPACLink", #ft2232_layout oocdlink, #ft2232_vid_pid 0x0403 0x6010

2) Instead of interface ft2232 line write interface jlink

You can also load u-boot using ddr stress test tool,please refer link.

Instead of 6,7 step you can follow following steps on j-link commander:

1) h
2) loadbin u-boot.bin 0x17800000
3) SetPC 0x17800000
4) wreg CPSR 0x000001d3
5) g

Let us know in case of any concerns.

Regards,

Karan Gajjar
