How do you enable Fastboot in u-boot for i.MX6Q boards

[michaelworster]

I've read on a few different sites, ex: Factory flashing with U-Boot and fastboot on Freescale i.MX6 , that's it's possible to enable Fastboot in the u-boot bootloader for i.MX6 products. I attempted to add the correct configuration options into the include/configs/mx6sabresd.h header file, but for some reason the built u-boot.imx still doesn't have the fastboot tool enabled.

Is there any information, wikis, or places where it's listed out what needs to be done to enable fastboot in the bootloader for the SABRE i.MX6Q board?

Hi all,

I'm facing the same issue of fastboot not identifying the deviceUSB_controller when flashing Yocto based Linux image.

Tool to flash : https://github.com/NXPmicro/mfgtools (UUU)

In u-boot I added the fastboot support, by using details at : https://bootlin.com/blog/factory-flashing-with-u-boot-and-fastboot-on-freescale-i-mx6/

But now the u-boot command fastboot is giving the error :

Run bootcmd_mfg: run mfgtool_args; if test ${tee} = yes; then bootm ${tee_addr} ${initrd_addr} ${fdt_addr}; else bootz ${loadaddr} ${initrd_addr} ${fdt_addr}; fi;
Hit any key to stop autoboot: 0
Bad Linux ARM zImage magic! 
=> fastboot
fastboot - use USB Fastboot protocol

Usage:
fastboot <USB_controller>
- run as a fastboot usb device
=> fastboot 0
g_dnl_register: failed!, error: -12
exit not allowed from main input shell.
=> fastboot 1
g_dnl_register: failed!, error: -12
exit not allowed from main input shell.

I'm new to the NXP IMX6 environment, kindly help with your inputs on :

1. emmc_burn_all.lst file to flash : u-boot.imx   ->     zImage  ->   imx6qd-nano.dtb    ->     fsl-image-gui-imx6qdnano.sdcard

2. How to use uuu -s to enter FB: ucmd  commands to flash IMX6 ?

Hi,

Very easiest way to remove fastboot LOCK from u-boot is comment out one line from "include/configs/mx6sabreandroid_common.h"

/* #define CONFIG_FASTBOOT_LOCK */            <<------------------ Only change required.

build the u-boot.imx thats it. Fastboot is enabled.

Hi Michael,

Are you going to use fastboot command like flash/erase on an MMC, NAND or NOR flash? Have you tried the following settings given in this thread?

Enable fastboot for MX50 RD3 board -blog archive

Hope this will be helpful.

Radike,

    Thanks for your reply, I attempted to use the patch as you suggested but after applying it there were a number of additional build failures. Finally I took a "simple" route and simply included the mx6sabreandroid_common header file which resided within include/configs as can be seen from the below patch file:

diff --git a/include/configs/mx6sabresd.h b/include/configs/mx6sabresd.h
index d9a699d..f327928 100644
--- a/include/configs/mx6sabresd.h
+++ b/include/configs/mx6sabresd.h
@@ -34,6 +34,7 @@
#endif
#include "mx6sabre_common.h"
+#include "mx6sabreandroid_common.h"

After doing this, the build finished successfully and I was able to access the "fastboot" command from the u-boot prompt. Windows also detected the device to be an "Android ADB Interface" when it booted via RAM.

I'm thinking this isn't a full solution due to the following messages:

unsupported boot devices
check_and_clean: reg 0, flag_set 0
Fastboot: Normal
SATA isn't buildin
Net:   FEC [PRIME]
Boot from USB for mfgtools
Use default environment for                              mfgtools
Run bootcmd_mfg: <NULL>
=>

and the fact the device didn't boot to Linux. But a step forward at least...

Hi,

Did you ever manage to get this to work?

Best,

[igorpadykov]

Hi Michael

please check attached document sect.8.2 How do I use Android fastboot?

Also it is recommended to look at i.MX6DQ Reference Manual

Chapter 8 System Boot

http://cache.freescale.com/files/32bit/doc/ref_manual/IMX6DQRM.pdf

and

imx6q, eMMC fast boot

Best regards

igor

Thanks for your reply Igor, unfortunately I'm not talking about this "eMMC Fast Boot" feature which is noted in the documents and on the other thread, but rather "fastboot" the utility for flashing a device, which has nothing to do with boot time.

See thread here: Factory flashing with U-Boot and fastboot on Freescale i.MX6

The patch on that site doesn't work directly, but that's the idea I'm trying to accomplish. I've read on a few similar pages that it does work on i.MX6 devices, but no concrete examples and I haven't gotten the u-boot to recognize the "fastboot" command yet.
