USB boot from Apalis iMX8QM USB01 on custom carrier board

Technical Support
, , , ,
1

We are testing the USB ports on our custom carrier board for the Apalis iMX8. We have designed USBO1, USBH2 and USBH3 to all be USB host ports. (USBH4 is unavailable at the moment.)

In Linux, we are able to use devices connected to any of the three ports. However, in u-boot, we are unable to use any of the ports:

  • USBH2 & USBH3 apply power to the device but “usb reset” in u-boot shows that USB0 is unavailable and USB1 has some sort of hub attached.
  • USBO1 does not apply power to the device

Any ideas on how I can get one of these ports to work in u-boot? I would prefer to use USBO1, but could live with using either of the other ports.

2

I see that the u-boot device tree has dr_mode="peripheral" in /usb@5b0d0000 which I think is keeping USBO1 from being used. I tried

fdt rm /usb@5b0d0000 dr_mode

and that opens the USB 0 bus for scanning, but power is still not applied to the USB stick.

Any ideas as to how to get power applied to USBO1?

3

It appears that USBO1_EN (pin 274) is not configured in the u-boot device tree. If I set GPIO4_IO03, then power is applied to the USB stick.

The following steps appear to get the Easy Installer on the USB stick to start:

fdt addr $fdtcontroladdr
fdt rm /usb@5b0d0000 dr_mode
gpio set 131
run bootcmd_usb0

I have not tried to install anything using autoinstall since I do not want to get this module stuck in an un-upgradable state like another module I have used ( awaiting resolution to issue raised in Making a bootable Torizon / EasyInstaller USB for Torizon 5 & iMX8 )

4

It sounds strange. pin 247 is used as USBO1_EN on Ixora board () and USB devices inserted to X8A lower connector work as expected.

Could you please clarify which exactly DT files you referred saying " pin 274 is not configured in the u-boot device tree "

5

I think this may be an issue relating to “U-Boot 2018.03-toradex_imx_v2018.03_4.14.98_2.3.0_bringup”, which is currently installed in the module.

I have not been able to try the newer u-boot; see here for more information.

6

Could you flash latest OS image using Toradex Easy Installer 2.0b6?

7

I was able to flash the Reference Minimal Image built from your instructions

The installed image boots and runs apparently normally but I am unable to flash any new images.

I tried running bootcmd_usb0 and the following is the result:

It looks like the u-boot installed by the update has one or more incorrect addresses set.

I tried to work around this problem by continuing as follows:

Apalis iMX8 # setenv ramdisk_addr_r 0x8a000000
Apalis iMX8 # setenv fdtfile        fsl-$fdtfile

Welcome to the Toradex Easy Installer

This is a Linux based installer for Toradex modules. Currently, the installer
does not have a serial console interface. You can use the Toradex Easy Installer
via any of the available display interfaces using USB mouse/keyboard or via a
network connection using VNC. Use:
  # ip addr show eth0
to display the Ethernet IP address or use USB RNDIS at IP 192.168.11.1.

On the HDMI monitor, it shows an error: Reading Config Block failed.

I now have two modules in this same stuck state.

I have tried using recovery mode to reinstall the Easy Installer. The recovery batch file starts okay, on the console I see u-boot start, but then it stalls at Hit any key to stop autoboot: 0

How can I update u-boot and linux on these modules?

8

Do you have an Ixora board? Can you use it to install latest version of Toradex pre-built image? And then test it with your carrier board?

9

I have an Apalis evaluation board that I have been trying to use to recover the modules, without success. Please see this message.

10

I could never get the Windows recovery batch file to work, but the Linux one does seem to work.

I was able to flash the Easy Installer, but the recover u-boot does not appear to properly enable the Ethernet port so I am unable to install anyversion of Toradex pre-built image.

11

Window recovery batch file works perfect for me. Are you using Windows 10?

What was a version of Easy Installer you flashed?

You can download an image from our website and put on USB stick or SD card .

12

Yes, Windows 10. For me, most of the time it would write the u-boot environment and then stop, but sometimes it would not do anything at all.

Easy Installer version: Apalis-iMX8_ToradexEasyInstaller_2.0b6-20201102

13

According our records you should have an Ixora carrier board. Could you try to replicate this issue using an Ixora board?

14

Using a different Windows 10 computer and the Ixora carrier board, I am able to use the Windows recovery batch file.

Not sure if the problem is a configuration problem with the original Windows 10 computer or with the Apalis carrier board interacting with Windows 10…

15

Thank you for an update.
