[U-Boot] login-password.

Dear Fabio, I hope you and all members of denx are good and wish you healthy life.. After studying and testing too many things, I managed our i.mx6dl board to boot rootfs with nfs. Then I see the login/password queries at the terminal as following lines. I entered the ROOT/root as login and empty(enter) for password as explained in the i.mx6 linux users manual, but it did not work. May be you know the login/password or a method to bypass this query in u-boot or kernel files. Thanks for your helps and Best regards.

[U-Boot] [PATCH] watchdog: mx25: use the imx_watchdog driver for mx25
by Martin Kaiser 21 Jul '18

21 Jul '18

From: Martin Kaiser <martin(a)kaiser.cx> The existing imx_watchdog driver is compatible with mx25 chipsets. Add a WDOG1_BASE_ADDR define for the base address and enable the driver in watchdog's Makefile. To use the driver, a board must define CONFIG_IMX_WATCHDOG and CONFIG_HW_WATCHDOG. This fixes an issue when booting an mx25 chip via usb/serial. In this case, the boot rom will always enable the watchdog. If u-boot is running in interactive mode and the watchdog is not serviced, the system is rebooted when the watchdog expires.

[U-Boot] Support of kernels > 16 MiB on Raspberry Pi
by Alexander Kurtz 21 Jul '18

21 Jul '18

Hi! I am using U-Boot to boot Debian Buster arm64 (standard kernel with a dracut-based initramfs) via an extlinux.conf on my Raspberry Pi 3. Recently, the Debian kernel grew beyond 16 MiB: 4.13: /boot/vmlinuz-4.13.0-1-arm64 == 16448000 bytes (< 16 MiB) [0] 4.14: /boot/vmlinuz-4.14.0-3-arm64 == 17539584 bytes (> 16 MiB) [1] 4.15: /boot/vmlinuz-4.15.0-1-arm64 == 17867264 bytes (> 16 MiB) [2] https://github.com/u-boot/u-boot/blob/master/include/configs/rpi.h#L129 says: #define ENV_MEM_LAYOUT_SETTINGS \ "fdt_high=ffffffff\0" \ "initrd_high=ffffffff\0" \ "fdt_addr_r=0x00000100\0" \ "pxefile_addr_r=0x00100000\0" \ "kernel_addr_r=0x01000000\0" \ "scriptaddr=0x02000000\0" \ "ramdisk_addr_r=0x02100000\0" \ Am I correct in assuming that this default configuration will break with kernels > 16 MiB? The Readme [3] seems to confirm this, but I wanted to ask for explicit confirmation here. The background is that ever since the upgrade to 4.14, the kernel has been failing to unpack the initramfs, complaining about "junk in [the] compressed archive" and I am currently trying to find where to best file a bug report about this!

[U-Boot] [PATCH 0/2] arm: zynq: add support for the zybo z7 board
by Luis Araneda 21 Jul '18

21 Jul '18

This series adds support for the Digilent Zybo Z7 board The only think, that I tested, and is not working yet, is reading the MAC address from the OTP region of the SPI flash memory, but I pretend to work on that I decided to split this series in two patches because the first contains the ps7_init_* file generated by Vivado and is ~170 kB. I tried to strip as much as possible from the file (from ~520 kB), but I wanted to preserve Vivado's comments to compare its output on future versions (it might have bugfixes). If the patch doesn't make it to the mailing list, I hope to find another solution, or I'll just simply remove additional content (Vivado's comments) Luis Araneda (2): arm: zynq: add ps7_init file for zybo z7 arm: zynq: add support for the zybo z7 board arch/arm/dts/Makefile | 3 +- arch/arm/dts/zynq-zybo-z7.dts | 91 + board/xilinx/zynq/zynq-zybo-z7/ps7_init_gpl.c | 3959 +++++++++++++++++ configs/zynq_zybo_z7_defconfig | 68 + 4 files changed, 4120 insertions(+), 1 deletion(-) create mode 100644 arch/arm/dts/zynq-zybo-z7.dts create mode 100644 board/xilinx/zynq/zynq-zybo-z7/ps7_init_gpl.c create mode 100644 configs/zynq_zybo_z7_defconfig -- 2.18.0

[U-Boot] [PATCH] binman: ensure temp filenames don't collide
by Stephen Warren 21 Jul '18

21 Jul '18

From: Stephen Warren <swarren(a)nvidia.com> The U-Boot Makefile can invoke binman multiple times in parallel. This is problematic because binman uses a static hard-coded temporary file name. If two instances of binman use that filename at the same time, one writing one reading, they may silently read the wrong content or actively detect missing signatures and error out the build process. Fix this by using a PID-specific filename instead.
