[U-Boot] [PATCH v3] i.mx: i.mx6q: add the initial support for i.mx6q Sabre Lite board
From: Jason Liu jason.hui@linaro.org
Add the initial support for Freescale i.MX6Q Sabre Lite board
Signed-off-by: Dirk Behme dirk.behme@de.bosch.com CC: Jason Liu jason.hui@linaro.org CC: Eric Nelson eric.nelson@boundarydevices.com --- V3: Add a readme. Enable the usboh3 clock: Bits 0 and 1 of CCM_CCGR7 are the usboh3 clock enable bits. Enabling this clock is necessary for the USB download:
-DATA 4 0x020c4080 0x000003FC +DATA 4 0x020c4080 0x000003FF
V2: change the default script to let linaro image boot, and also change the default env to dev 0, which is normal SD slot, not the Micro-SD slot

Good question ;) There is some discussion if it is possible to make a new version of the board which is configurable to SD boot by HW. But there seem to be some layout issues. So atm I would answer your question with 'no'.

Good question ;) There is some discussion if it is possible to make a new version of the board which is configurable to SD boot by HW. But there seem to be some layout issues. So atm I would answer your question with 'no'.
To clarify, all SabreLite boards produced to date have their boot fuses blown to select boot to SPI NOR. In the future, this could be changed to allow boot to SD, but that's a one-time choice.
The layout issues concern the use "Internal Boot Mode", which allows a set of ~32 GPIOs to override the fuse settings, which will require a bunch of pull-up/down resistors.

Unfortunately, at the moment you have to ask your Freescale contact for this. We ping Freescale since weeks for this. Last time I heard about this Freescale planned to release this binary under a BSD license. They are still "working through the licensing details", though :(
What means early version of SabreLite boards?
Most probably Eric will be able to better answer this.
What I understood: Up to now, the boards boot from SPI NOR by default. There was some _discussion_ to change this to SD boot. Most probably "early version" was written while this discussion under the impression that later boards might switch to SD boot. To my understanding the result of this discussion was that this change would be difficult, though.
How can I select boot from SD-Card on newer versions?
To my understanding there are no "newer versions" yet.
And will the u-boot.imx image also boot when loaded to the SPI-NOR fash?
Hmm, I'm not sure about this as I haven't tested this.
Eric?
Please note that Eric is in the process of mainlining the SPI driver for i.MX6, atm.
Best regards
Dirk

Unfortunately, at the moment you have to ask your Freescale contact for this. We ping Freescale since weeks for this. Last time I heard about this Freescale planned to release this binary under a BSD license. They are still "working through the licensing details", though :(

At this point **all** versions of SabreLite are configured to boot to SPI NOR through the fuses.
As Dirk mentioned, we've had some conversations about booting to SD card, but once the fuse is blown, it's blown.

We've discussed, but currently have no plans to support a physical switch to control this decision. This would involve using the "Internal" boot mode position of SW1 and then pulling a **bunch** of pins high or low to control the boot flow.
Note that all of the pins are available on connector J12 (BOOT/EIM), so it might be done with a small daughter-board.

Yes. If you program u-boot.imx to offset 0x400, it will boot.
I just did so as shown below.
I started by placing SW1 in the 01 position (boot to USB), and used imx_usb to dowload u-boot.imx:

The imx_usb utility is available here: http://boundarydevices.com/git?p=imx_usb_loader.git
It requires libusb-1.0-0-dev to build, but has few other dependencies.
Usage is simple: hand it the file you want to execute. It will look at the header to find out where to place the image. ~/imx_usb_loader$ sudo sudo ./imx_usb u-boot.imx
Please note that Eric is in the process of mainlining the SPI driver for i.MX6, atm.
If you use my latest patch set, you can place the environment in SPI-NOR as well by commenting out CONFIG_ENV_IS_IN_MMC, and un-commenting ..._IN_SPI_FLASH in include/configs/mx6qsabrelite.h.

Eric

OK, I see.

But above you used the network to load u-boot.imx. With imx_usb you loaded and booted an image via USB first, I assume.

Nice fallback in case the bootloader does not start. I will give it a try a.s.a.p. We actually plan to use a BDI[23]000 for that purpose.

OK, that's already an excellent starting point.
Thanks.

Yeah. USB to execute U-Boot, then Ethernet to get a pristine image into RAM for programming.
I'd love to get USB support for MX6Q into U-Boot, but that's another project...
