Message-ID: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Hi everybody, hope you are doing well, my name is Nicol?s Muratore from Argentina, I'm doing I development under imxrt1020 EVK, I did test many "bare metal" programs to run from SD and those work ok on this EVK, right now I'm thinking to work with u-boot over imxrt1020 EVK, but I have problems to boot the u-boot from SD, I've followed the entire procedure from web page https://u-boot.readthedocs.io/en/stable/board/freescale/imxrt1020-evk.html: I'm using Ubuntu 18.04 and gnu-arm-linux-gnueabi cross compiler. 1) I have installed the u-boot package with all dependencies and gcc-arm-linux-gnueabi compiler. 2) #sudo make mr proper 3) #sudo make imxrt1020-evk_defconfig 4) #sudo CROSS-COMPILE=arm-linu-gnueabi- make 5) it compiles without errors, I can see the SPL file and u-boot.img, and other related files, (I attached all output files to this email).. 6) Copy files to SD: #sudo dd if=SPL of= /dev/sdb bs=1k seek=1 conv=notrunc ; sync // This process copy "SPL" file on SD card with no errors. 7) Copy files to SD: #sudo dd if=u-boot.img of= /dev/sdb bs=1k seek=128 conv=notrunc ; sync // This process copy "u-boot.img" file on SD card with no errors. After the copy process I put the SD on the imxrt1020 EVK, the SW7 in 0110 (I have tested the EVK many times using "bare metal" and it is ok). I connect the USB console cable to the PC like I always do, but I can't see anything, it seems to be that the u-boot doesn't run. Would you have any idea what is going on? I really appreciate your help, sorry to bother you, but I'm breaking my mind thinking why this doesn't run on my EVK. Many thanks. -------------- next part -------------- A non-text attachment was scrubbed... Name: u-boot-imxrt1020.zip Type: application/zip Size: 1038233 bytes Desc: not available URL:
