Error on stock u-boot/fastboot - Unknown command 'source'

Products Support Poplar Board
#1

I am having an issue on the last step of the build and flash instructions:
https://github.com/Linaro/poplar-tools/blob/latest/build_instructions.md

Seems the stock fastboot/u-boot does not recognize the “source” command:

 usb reset
 fatload usb 0:1 ${scriptaddr} install.scr
 source ${scriptaddr}

Did not work so I ran the older commands and got to the last step:

usb reset
fatsize usb 0:1 install.scr
fatload usb 0:1 0x07000000 install.scr
source 0x07000000

fastboot# source 0x07000000                                                
Unknown command 'source' - try 'help'

Maybe use setenv?

setenv source ${scriptaddr}

usb reset
setenv scriptaddr 0x07000000
setenv source ${scriptaddr}
saveenv
fatload usb 0:1 ${scriptaddr} install.scr

I’ll try this in a few…

Did not work.

Here is full output of how the instruction are written now:

Getting closer… Just need to execute the install.scr script but how without ‘source’ command…

   fastboot# usb reset

So just a bit of research shows that the current fastboot/u-boot that comes preinstalled on poplar has no support for the source command built into u-boot.

define CONFIG_CMD_SOURCE=y

#6

I’m going to try to tftp the new u-boot/l-boot next chance I get. In the meantime any pointers would be appreciated :wink:

You can download the images over TFTP after setting the network parameters:

setenv serverip xxx.xxx.xxx.xxx
setenv ipaddr xxx.xxx.xxx.xxx
setenv gatewayip xxx.xxx.xxx.xxx
setenv ethaddr 00:xx:xx:xx:xx:xx
setenv netmask 255.255.xxx.0

To download the boot image:

    mw.b 1000000 ff 80000                       //Write 0xff to 0x1000000. 0x80000 space is used.
    tftp 1000000 fastboot-burn.bin              //Download fastboot-burn.bin to 0x1000000.
    nand erase 0 100000                         //Erase the 0x100000 flash space after the 0x0 address.
    nand write 1000000 0 80000

I’m afraid I only really have experience with the (new) 64-bit u-boot.

However, what I can assure you is that can experiment with that non-destructively. If fastboot.bin is copied to a FAT32 partition on a USB stick then the poplar boot ROM can be made to load that by holding down the USB_BOOT button. This allows you to experiment with what is (and isn’t) supported by the 64-bit version without altering eMMC (just make sure you say “No” when asked if you want to do the install… or just git revert 1de155d0a).

The 64-bit u-boot does not currently support the built-in network interface (although I think networking can be achieved via USB). More importantly using USB means it supports the regular distro mechanisms of a modern u-boot (i.e. it fetches extlinux/extlinux.conf automatically from USB and uses that to launch a kernel).

I’ve used this feature to construct a proof-of-concept installer that loads Linux and a buildroot userspace (this could also be used to backup the original contents of eMMC if you wanted to… although I didn’t actually bother with that myself).

The same distro mechanisms remain in place once u-boot is burned to eMMC. It will try USB first and if it does not find a suitable extlinux.conf it will go looking on the eMMC instead.

#8

So you are saying I can put the newest uboot/lboot on a USB drive rename it to fastboot.bin and press USB button to load and flash new u-boot??

#9

Almost… if you just drop fastboot.bin onto a USB stick that you will make that stick bootable by poplar, subject to some restrictions on partitioning and filesystem. If you drop only fastboot.bin on the stick then the rest of the installer will be missing (so I wouldn’t advise saying “YES” if it asks you if you want to install u-boot).

However, if you say anything except YES then u-boot will run its distro boot protocols (including a boot auto-delay if you just want to poke about at the prompt.

If you augment fastboot.bin with extlinux/extlinux.conf (appropriately configured), Image and ramdisk.cpio.gz in the same filesystem then you can boot the kernel from USB.

#10

Okay so I created the USB with the poplar tools and this has the new l-boot so I can press USB and yes to update mmc with the full usb_recovery.img correct?

#11

Yes. This will install (a slightly tailored) debian stretch together with ARM trusted firmware, bootloader and kernel. There is pretty limited hardware enablement right now.

I guess I should also note (if not for you then for other interested readers) that after saying YES the action will be very difficult to reverse. I don’t think there are any tools available to help restore the original partitioning and images.

#12

That is good to know. So lets say if one wanted to test the u-boot/l-boot (without committing to writing to flash) you would press USB_BOOT button then type anything BUT “YES” at the prompt and the poplar will just boot and run from USB. Correct?

Very good to know when testing other OS’s…

#13

Tocoding has images available to restore the original image. They are available at: http://www.tocoding.com/index.php/96board-hitv/

I also see that they are now linking to the Linux Release on GitHub.org/Linao.

#14

Lets just say that I chose the word “difficult” with some care!

For sure it is not impossible… but there are no flashing tools to help. The user would need to author their own USB image and hand craft all the fatload/mmc write commands for themselves!

#15

My own scripts for non-destructive fiddling look something like this:

#!/bin/sh

# Currently guestfish offers no way to force FAT32 when creating a vfat
# filesystem. The poplar boot ROM only supports FAT32 so we have to
# pre-format the boot filesystem.
guestfish sparse poplar-install.img 63M

rm poplar-install.img
rm extlinux.conf

I’ve been using buildroot build and this script is the final step in the build process (using BR2_ROOTFS_POST_IMAGE_SCRIPT="./generate-media.sh"). The only other thing about my buildroot that is at all interesting is the overlay directory (BR2_ROOTFS_OVERLAY="./overlay") where I’ve copied fastboot.bin, a kernel and a dtb.

The overlay directory is not just used to construct the media, it is also copied into the initial ramdisk (so I can install stuff to eMMC if I want).

BTW I’m not trying to drip feed information here. This stuff was all put together as a proof-of-concept and I’ve not tied it up nicely for anyone to play with (?yet?).

#16

I managed to flash the newer u-boot/l-boot using USB_BOOT button and now I can see the u-boot prompt but the script failed to flash the linaro stretch to internal mmc.

This error repeats over and over. No worries tho as long as u-boot is there I can use extlinux.conf to load an OS :wink:

I have a problem with this last step too. When I run:
fatload usb 0:1 ${scriptaddr} install.src
it shows:
reading install.src
** Unable to read file install.src **

#18

Tried the updated instructions, not even working unknown command “source” yet again…

#19

@mattgorski I’ve been using the updated instructions (https://github.com/Linaro/poplar-tools/blob/latest/build_instructions.md) for ~2 months now without issues. Have you tried flashing the latest build first using USB_BOOT?

#20

@mattgorski: Can you provide the full boot logs in a pastebin somewhere?
