U-boot-at91 prints strange characters #31

SimoneBongini · 2023-06-21T08:21:38Z

Hello

I'm using an ArrowElectronic Shield96 boad which based on SAMA5D27_SIP.

I was able to build:

at91bootstrap (4.0.5+gitAUTOINC+8fe4b67188-r0 )
at91 u-boot (v2022.01-at91+gitAUTOINC+76f7f55e04-r0)
at91 linux kernel (5.15+gitAUTOINC+5aedde3bc3-r0)
rootFS

obtaining a .wic image.
After flashed successfully the SDCard with balenaEtcher, I got that the U-boot print strange characters.

Then kernel start normally.
I noticed
serial_atmel serial@f8020000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19

I'm using, more or less, a sama5d27_som1_ek devices tree, so it should be defined correctly.
Seems u-boot change serial baudrate. Is it possible?

The text was updated successfully, but these errors were encountered:

It looks like your USART registers are configured very differently. Could you send a copy of your u-boot.bin and uboot.env Are you using USART1 for the serial output? Could you also try a full clean rebuild for the whole project?

ryan-wanner · 2023-09-06T13:40:47Z

Hi Simone,
Booted up your u-boot.bin file I do see the correct output in 115200. Did you make any changes to the device tree in uboot? Based on this error I see that you get "serial_atmel serial@f8020000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19" I think you might have the pinctrl wrong on the dts file

Hello Simone,
After looking at the schematics for the shield96 I see that you have a 12MHz crystal oscillator. You need to go into the at91bootstrap menuconfig then inside the clock signals menu navigate to main crystal configuration then select crystal frequency and select 12MHz. Then make sure that the device tree in u-boot, sama5d27_som1.dtsi, the main_xtal frequency is set to 12MHz. This should match with your original dtsi file you had for linux that has the main xtal set at 12MHz.

See if this helps

Ryan

Hello Ryan, thanks a lot for the feedback.
Yes, shield96 have a 12MHz crystal oscillator. I have already set main_xtal to 12MHz. But the problem persists.
Find attached:

at91bootstrap config (sama5d27_sd96sd_uboot_defconfig
sama5d27_sd96sd_uboot_defconfig.zip )
u-boot-at91 defconfig and devicestrees
u-boot.zip
at91-linux defconfig and devicetree linux.zip

I'm using.
Find below the serial log I got: log.txt.txt

Hello Simone,
When I use your config files you gave me I do get the correct u-boot output. I think there is an issue with the UART initialization in either at91bootstrap or u-boot. I do recommend to visit this link HERE and make a free account. You will be able to get more timely responses and more focused help.
