09:01 <wooosaiiii> I have imx8mn chip... it boots the flash.bin binary which contains SPL, DDR, DTS and u-boot proper... DDR, DTS and u-boot are inside FIT image format, right? Is it possible to somehow check in SPL if those binaries are not corrupted? Like checksum/crc32 etc?

10:37 <clarity> fit images can have hashes

10:37 <clarity> (signatures too)

10:43 <wooosaiiii> clarity: OK, thanks... I figured out I can add hash algo to its...

10:46 <wooosaiiii> side questions.... with iMX8M, is there any way of checking / recovering from flash.bin binary corruption?

10:50 <wooosaiiii> maybe HABv4... but I am not sure what happens on closed devices for example when eMMC's boot0 flash.bin is corrupted... will ROM switch to eMMC's boot1 flash.bin image or ?

11:07 <wooosaiiii> put another way... is it possible to recover (detect) flash.bin corruption (especially SPL + DDR FW part of it) on iMX8M?

12:32 <senzilla> Question about dts building... In the source tree I find lots of *-u-boot.dtsi files. But I cannot see where these get included (or overlaid) with their dts counterpart. Could anyone give me pointers?

12:33 <senzilla> My goal here to simply understand the build system a bit better

12:33 <j`ey> senzilla: theyre included by other files arent they?

12:34 <senzilla> Not that I can see. Let's take this as an example:

12:35 <senzilla> Here is the main dts for Pinebook Pro: https://github.com/u-boot/u-boot/blob/master/arch/arm/dts/rk3399-pinebook-pro.dts

12:35 <j`ey> for example arch/arm/dts/dra7-evm-u-boot.dtsi includes omap5-u-boot.dtsi

12:35 <senzilla> This does not seem to include this one: https://github.com/u-boot/u-boot/blob/master/arch/arm/dts/rk3399-pinebook-pro-u-boot.dtsi

12:36 <j`ey> senzilla: look at scripts/Makefile.lib cmd_dtc

12:37 <LeSpocky> w

12:37 <LeSpocky> .oO( wrong windows )

12:38 <senzilla> j`ey: yay! Thank you! This is exactly what I was looking for. I just couldn't figure out how the final dtb was assembled

14:37 <marex> wooosaiiii: use the two boot partitions I told you about last time ?

14:38 <marex> wooosaiiii: I think mkimage can verify flash.bin container, see mkimage -l
