hi
i am a newbie and my target is mcimx6sx-sdb (i.mx 6soloX proc).
i have need to place u-boot in qspi flash by J-Flash (i have to use "j-link pluse" device only, i can not use mmc/sd or usb-hid) and run it.
i can see Flash bank 0(QSPI Flash sytarts from 0x70000000 and end at 0x73FFFFFF) and i can load a bin file (but not a imx file, error "Unsupported file type *imx").
I have seen https://community.nxp.com/thread/340521 but i do not understand sense of some things.
could you tell me correct way flashing u-boot image onQuadSPA and run it .
Regards.

Hi Oleg

qspi programming with jtag is not supported by nxp, may be useful to look on

[SOLVED/OR] QSPI flash programming on iMX6SX - J-Link/Flasher related - SEGGER - Forum

Debugging using Segger J-Link JTAG - Boundary Devices

Best regards

have a good day Igor

i tried simple method-load uboot image by mfgtool and then save it a as bin file by J-Flash app. I realize that this is an unpromising way if i have to change target device configuration.
I see only one way - build my own u-boot image and load it to RAM by J-Link then move it to QSPI nor.
am i right?
Regards.
