Sometimes imximage throws the following error: MKIMAGE u-boot-dtb.imx Error: No BOOT_FROM tag in board/freescale/mx6sxsabresd/imximage.cfg.cfgtmp arch/arm/imx-common/Makefile:91: recipe for target 'u-boot-dtb.imx' failed Later on, when running mkimage for the u-boot.imx it will succeed in finding the IVT offset. Looks like some race condition happening during parallel build when processing mkimage for u-boot-dtb.imx and u-boot.imx. A proper fix still needs to be implemented, but as a workaround let's remove the error when the IVT offset is not found. It is useful to have such message, especially during bring-up phase, but the build error that it causes is severe, so better avoid the build error for now. The error checking can be re-implemented later when we have a proper fix. This workaround has already been applied in mainline U-Boot: http://git.denx.de/?p=u-boot.git;a=commit;h=b5b0e4e351e20a606de22db6a56ad6bc1e2aa8fd Fixes: https://gitlab.com/buildroot.org/buildroot/-/jobs/59015347 Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Fabio Estevam <festevam@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> |

******************************************************** Freescale i.MX6 Q, DL and SoloX SABRE development boards ******************************************************** This file documents the Buildroot support for the Freescale SABRE Board for Smart Devices Based on the i.MX 6 and i.MX 6SoloX Series (SABRESD), as well as the Freescale SABRE Board for Automotive Infotainment. Read the i.MX 6 SABRESD Quick Start Guide for an introduction to the board: http://cache.freescale.com/files/32bit/doc/quick_start_guide/SABRESDB_IMX6_QSG.pdf Read the i.MX 6 SoloX SABRESD Quick Start Guide for an introduction to the board: http://cache.freescale.com/files/32bit/doc/user_guide/IMX6SOLOXQSG.pdf Read the SABRE for Automotive Infotainment Quick Start Guide for an introduction to the board: http://cache.freescale.com/files/32bit/doc/user_guide/IMX6SABREINFOQSG.pdf Building with NXP kernel and NXP U-Boot ======================================= First, configure Buildroot for your SABRE board. For i.MX6Q SABRE SD board: make freescale_imx6qsabresd_defconfig For i.MX6DL SABRE SD board: make freescale_imx6dlsabresd_defconfig For i.MX6 SoloX SABRE SD board: make freescale_imx6sxsabresd_defconfig For i.MX6Q SABRE Auto board: make freescale_imx6qsabreauto_defconfig For i.MX6DL SABRE Auto board: make freescale_imx6dlsabreauto_defconfig Build all components: make You will find in ./output/images/ the following files: - imx6dl-sabresd.dtb or imx6q-sabresd.dtb or imx6sx-sdb.dtb or imx6q-sabreauto.dtb or imx6dl-sabreauto.dtb - rootfs.ext2 - rootfs.tar - u-boot.imx - uImage, or zImage for i.MX6 SoloX Building with mainline kernel and mainline U-Boot ================================================= Mainline U-Boot uses SPL and can support the three variants of mx6sabreauto boards: mx6q, mx6dl and mx6qp. First, configure Buildroot for your mx6sabreauto board make imx6-sabreauto_defconfig Build all components: make You will find in output/images/ the following files: - imx6dl-sabresd.dtb, imx6q-sabresd.dtb, imx6q-sabresd.dtb - rootfs.ext2 - SPL and u-boot.img - u-boot.imx - zImage Create a bootable SD card ========================= To determine the device associated to the SD card have a look in the /proc/partitions file: cat /proc/partitions Buildroot prepares a bootable "sdcard.img" image in the output/images/ directory, ready to be dumped on a microSD card. Launch the following command as root: dd if=./output/images/sdcard.img of=/dev/<your-microsd-device> *** WARNING! The script will destroy all the card content. Use with care! *** For details about the medium image layout, see the definition in board/freescale/common/imx/genimage.cfg.template. Boot the SABRE board ==================== i.MX6 SABRE SD -------------- To boot your newly created system on an i.MX6 SABRE SD Board (refer to the i.MX6 SABRE SD Quick Start Guide for guidance): - insert the SD card in the SD3 slot of the board; - locate the BOOT dip switches (SW6), set dips 2 and 7 to ON, all others to OFF; - connect a Micro USB cable to Debug Port and connect using a terminal emulator at 115200 bps, 8n1; - power on the board. i.MX6 SoloX SABRE SD -------------------- To boot your newly created system on an i.MX6 SoloX SABRE SD Board (refer to the i.MX6 SoloX SABRE SD Quick Start Guide for guidance): - insert the SD card in the J4-SD4 socket at the bottom of the board; - Set the SW10, SW11 and SW12 DIP switches at the top of the board in their default position, to boot from SD card. Reference configuration: SW10 1 2 3 4 5 6 7 8 off off off off off off off off SW11 1 2 3 4 5 6 7 8 off off ON ON ON off off off SW12 1 2 3 4 5 6 7 8 off ON off off off off off off - connect a Micro USB cable to the J16 Debug Port at the bottom of the board. This is a dual UART debug port; connect to the first tty using a terminal emulator at 115200 bps, 8n1; - power on the board with the SW1-PWR switch at the top of the board. SABRE Auto ---------- To boot your newly created system on a SABRE Auto Board (refer to the SABRE for Automotive Infotainment Quick Start Guide for guidance): - insert the SD card in the CPU card SD card socket J14; - Set the S1, S2 and S3 DIP switches and J3 jumper to boot from SD on CPU card. Reference configuration: S1 1 2 3 4 5 6 7 8 9 10 off ON off off ON off off off off off S2 1 2 3 4 off off ON off S3 1 2 3 4 off off ON ON J3: 1-2 - connect an RS-232 UART cable to CPU card debug port J18 UART DB9 and connect using a terminal emulator at 115200 bps, 8n1; - power on the board.
