(Sorry if this sounds like nitpkicking, but I am genuinely curious) How is it supposed to work? You need not only https but also verify the presented certificate chain, and for that you need up-to-date root certificates (e.g. the bundle available from mozilla). This sounds a bit outside the scope of u-boot to me (or you should avoid the man-in-the-middle argument, which leaves the still valid "sites stop offering plain http" argument). If you really worry about man-in-the-middle you need to download via https in an environment that does certificate validation, and then even better verify the hash of the downloaded image. After that you can offer the image locally - via http, https or tftp - for installations. Martin

It was a toolchain issue and with a bit of help I now have a boot.bin and a u-boot.img from 2022.10, but both are happily ignored by the board when booting. Do I need to set something special to make it boot from SD card instead of SPI flash? Martin

Adapteva Parallella board
Hey folks, the other day I was asked to test some changes on my Adapteva Parallella board, which I hadn't used for ages. I noticed it has an ancient u-boot: U-Boot 2012.10-3-g792c31c (Jan 03 2014 - 12:24:08) I2C: ready DRAM: 992 MiB WARNING: Caches not enabled MMC: SDHCI: 0 SF: Detected N25Q128 with page size 64 KiB, total 16 MiB In:serial Out: serial Err: serial Net: zynq_gem Hit any key to stop autoboot: ... and a quick search turned up lots of supported similar boards in u-boot mainline under board/xilinx/zynq - but no concrete instructions or test results for the Parallella. Anyone know what would be missing or is it just something simple like "take u-boot for z702 and replace the dtb"? Martin

Use printf(3) to convert to/from hex, and standard shell arithmetic with $(( )). Looks horrible, but something like: v=$(( $( printf "%d\n" 0xa0 ) + $( printf "%d\n" 0x10 ) )) printf "v = %d (%x)\n" $v $v ... maybe arranged into some sh helper functions.

[U-Boot] board/amlogic/odroid-c2/README - how to make the instructions more portable?
Hi folks, I am trying to get a new u-boot on my Odroid C2 following the instructions in board/amlogic/odroid-c2/README. Unfortunately these tell me to use not only the vendor provided blobs, but also their tools. This is painfull: file $DIR/fip/fip_create odroid-c2/fip/fip_create: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=0dc4b0e1bd118ffc3c0f77e815b6d86acc1f25c2, not stripped so I need to set up an environment where I can run that. There are alternatives, so the instructions should probably be updated to use them. I have "fiptool" from ARM trusted firmware v2.0, and "fiptool create" should be able to do what fip_create did. Also I have meson-tools installed, providing amlbootsig which could replace aml_encrypt_gxb. Has someone used these alternate tools instead of the vendor binaries? How do the fip_create options from the README translate to fiptool? Martin ___ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
[U-Boot] [PATCH] tools: improve portability of imx_cntr_image.sh
Replace non-portable operator == with =
The operator == in sh(1) / test(1) is non-POSIX and only implemented by
some shells (like bash). It is equivalent to the standard defined operator =.

[U-Boot] Portability of sh scripts
Hey folks, I noticed that tools/imx_cntr_image.sh contains non-portable code: if [ $f == "u-boot-dtb.bin" ]; then This is a "bash-ism", the operator "==" is not implemented by most test(1) or sh(1) impmlementations.

Why make it signed? "%zu bytes" should be better.

[U-Boot] Anyone using recentish u-boot on a GuruPlug?
I naively compiled a 2017.11 u-boot for GuruPlug and wrote the u-boot.kwb to nand, but that bricked the GuruPlug (should have tested with a ram version first, yes, I know). I have a jtag for it and was able to recover, but I wonder if i did something wrong in my local build or if support just bitrotted silently. I am not familiar with .kwb and early kirkwood bootstrap, so not sure how I could debug this, besides the jtag is "slightly fragile" and using it a bit inconvenient.
