imxrt1020 EVK u-boot doesn't run.
Hi everybody, hope you are doing well, my name is Nicolás 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.
Hi Nicolás,
Adding Giulio in case he has any ideas.

Hi Nicolas,
thank you Fabio for adding me, I’m going to give a try soon with imxrt1020-evk board and check, as well as with imxrt1050-evk.
It passed some time since I’ve added them to uboot and maybe something is broken now.
Also, if you then have further question ask me. Do you mean to run some OS after uboot?
Linux is still there waiting for someone interested on it, as well as uboot support for other peripherals.
PS: sorry for too posting but I’m on mobile.
Best regards Giulio Benetti —- Benetti Engineering s.a.s.

I've just entered debugging and two things came out: 1) in board/freescale/imxrt-1020-evk/imxrt1020-evk.c when calling spl_dram_init() there is some printf() inside that gets called, but that happens before calling preloader_console_init() that set serial up, so this is the reason why there is no output at all. 2) I've completely ignored(wrongly) having a timer and at that time u-boot allowed it getting a tick-count always at 0, so every delay called return immediatly with 0. This is not possible anymore and I need to finish writing gpt-timer driver I was writing.
So please let me finish that gpt-driver timer and I'll send patches to fix imxrt1020/50-evk.
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.
Best regards and happy easter! :-)

Can you please try to apply this patch [1] to check if uart starts to work and giving you this message [2]?

Thank you
Hi Giulio, hope this email finds you well, many thanks for your support.
After the modification that you proposed, the result was the following:
[image: imagen.png] yes it's the same message.
Please let me know when you have finished the timer driver.
Many thanks.

Ok, well,
Please let me know when you have finished the timer driver.
I need some time, I’ve created other patches but there is still something to be fixed. I’m close but I need some other time. I’m going to send patches soon.
Many thanks.
You’re welcome
Best regards Giulio
