To add the following define in file “./include/configs/nitrogen6_max.h”Īfter added the above define, I added the fbcon parameter in the “/proc/cmdline” as shown cat /proc/cmdlineįbcon=rotate:1 console=ttymxc1,115200 vmalloc=400M consoleblank=0 rootwait fixrtc cpu=6Q board=nitrogen6_max mxc_hdmi.only_cea=1 root=/dev/mmcblk0p1 wlcore.mac=00:19:b8:81:fc:28 splash plymouth.ignore-serial-consoles loglevel=4 reset_cause=0x1Īfter all the above work, the u-boot display is still cannot rotate. The Merge Window for the next release (v2022.10) is open until -rc1 release on Mon 25 July 2022. Sometimes, for example if the display is mounted in portrait mode or even if it's mounted landscape but rotated by 180degree, we need to rotate our content of the display relative to the framebuffer, so that user can read the messages which are printed out. U-Boot v2022.07 was released on Mon 11 July 2022. I need to rotate the u-boot console display message on the display connected to the system and so I follow the uboot file “README”, The generated file in this case will be u-boot.imx In this case lets use m圆qsabresd_configĤ - The binary file will be generated and will be located at project root folder. The U-boot project is developed and maintained by Denx Computer Systems can be downloaded in the following link:ģ - Check the name of the board on "configs" folder. In this example, lets use m圆qsabresdĥ - The binary file will be generated and will be located at project root folder. Check the exactly name of the choosen board and add "_config" to build the project.
#U boot imx code#

#U boot imx update#
This update applies to the following SOMs:įollow Variscite step by step guide on U-boot provided by Freescale can be downloaded in the following link:ġ - Set the cross compiler environment variables. When a customer wants to use a customized U-Boot of his own for his production process, instead of the default Variscite pre-programmed U-Boot or a customized U-Boot pre-programmed by Variscite.Recovering from a ‘brick’ state (when SPL/U-Boot are accidentally removed from the SOM’s internal storage) on an end product.In addition, all Variscite carrier boards have an SD card slot and allow the SOMs to be booted from an SD card (like Variscite’s recovery SD card).Īlthough this utility isn’t required by the majority of the Variscite customers, it provides a further method to boot Variscite’s SOMs.Ī popular example of using this utility is when the customer’s board design doesn’t include an SD card slot: It’s worth noting that all Variscite SOMs are shipped with SPL and U-Boot pre-programmed on the SOM’s internal storage. This new feature allows Variscite customers to enjoy the benefits of booting from USB, without missing out on the hardware modularity made possible by using SPL. Recently, a new feature has been added to imx_loader and to U-Boot – they now support consecutive loading of SPL and U-Boot via the USB OTG port. Most commonly it is used as a replacement for NXP’s MFGTOOL to load U-Boot via the USB OTG port.
#U boot imx serial#
This open-source utility software by Boundary Devices allows to download and execute code on NXP i.MX5/ i.MX6/i.MX7 and Vybrid SoCs through the Serial Download Protocol (SDP).
Variscite now supports a new, highly demanded feature: Boot SPL and U-Boot from USB, using the imx_usb_loader utility.
