Subject: Re: [PATCH V5 32/32] imx: add i.MX8QXP MEK board support
Hi Peng,
I am fine with most patches of this series.
Thanks.
Anyway, I see that to build the image
...
you are using a "fork" of mkimage...
Yes. I am developing the i.MX8X mkimage support in U-Boot.
I think It could catch up next release.
ok - thanks !
Best regards,
Stefano

Thanks,
Peng.

I took a look at the source code. We cannot even say that this was started by
NXP, because it is clearly based on the original U-Boot mainline code. Having
forked it, it is quite bad. We tried in the past to include tools (see i.MX / Atmel /
TI ..) into U-Boot code instead of using external tools, and it is a pity to revert
this back with i.MX8.
This is generally not accepted in mainline - can we revert and integrate this
imx-mkimage into U-Boot's mkimage tool ?
Best regards,
Stefano

+Generate flash.bin using imx-mkimage
+====================================



+Copy the following binaries to imx-mkimage/iMX8M folder:



+$ cp imx-atf/build/imx8qxp/release/bl31.bin imx-mkimage/iMX8QX/ $ cp
+u-boot/u-boot.bin imx-mkimage/iMX8QX/



+Copy the following firmwares to imx-mkimage/iMX8 folder :



+$ cp firmware-imx-7.6/firmware/seco/ahab-container.img
+imx-mkimage/iMX8QX/ $ cp imx-sc-firmware-0.7/mx8qx-mek-scfw-tcm.bin
+imx-mkimage/iMX8QX/scfw_tcm.bin



+$ cd imx-mkimage/
+$ make SOC=iMX8QX flash



+Flash the binary into the SD card
+=================================



+Burn the flash.bin binary to SD card offset 32KB:



+$ sudo dd if=iMX8QX/flash.bin of=/dev/sd[x] bs=1024 seek=32



+Boot
+====
+Set Boot switch SW2: 1100.

+Generate flash.bin using imx-mkimage
+====================================



+Copy the following binaries to imx-mkimage/iMX8M folder:



+$ cp imx-atf/build/imx8mq/release/bl31.bin imx-mkimage/iMX8M/ $ cp
+u-boot/u-boot-nodtb.bin imx-mkimage/iMX8M/ $ cp
+u-boot/spl/u-boot-spl.bin imx-mkimage/iMX8M/ $ cp
+u-boot/arch/arm/dts/fsl-imx8mq-evk.dtb imx-mkimage/iMX8M/



+Copy the following firmwares to imx-mkimage/iMX8 folder :



+$ cp
+firmware-imx-7.2/firmware/ddr/synopsys/lpddr4_pmu_train_1d_dmem.bin
+imx-mkimage/iMX8M/ $ cp
+firmware-imx-7.2/firmware/ddr/synopsys/lpddr4_pmu_train_1d_imem.bin
+imx-mkimage/iMX8M/ $ cp
+firmware-imx-7.2/firmware/ddr/synopsys/lpddr4_pmu_train_2d_dmem.bin
+imx-mkimage/iMX8M/ $ cp
+firmware-imx-7.2/firmware/ddr/synopsys/lpddr4_pmu_train_2d_imem.bin
+imx-mkimage/iMX8M/



+If you want to run with HDMI, copy signed_hdmi_imx8m.bin to
imx-mkimage/iMX8M.
...



+Before generating the flash.bin, transfer the mkimage generated by U-Boot
to iMX8M folder:
...



+$ cp u-boot/tools/mkimage imx-mkimage/iMX8M/ $ mv
+imx-mkimage/iMX8M/mkimage imx-mkimage/iMX8M/mkimage_uboot



+$ cd imx-mkimage/
+$ make SOC=iMX8M flash_spl_uboot



+Or for using HDMI:



+$ make SOC=iMX8M flash_hdmi_spl_uboot



+Flash the binary into the SD card
+=================================



+Burn the flash.bin binary to SD card offset 33KB:



+$ sudo dd if=iMX8M/flash.bin of=/dev/sd[x] bs=1024 seek=33



+Boot
+====
+Set Boot switch SW801: 1100 and Bmode: 10 to boot from Micro SD.
