[U-Boot] u-boot 2018 SPI SPL

[U-Boot] u-boot 2018 SPI SPL

[Mehmet Ali İPİN]

Dear Sir/Madam,

Hello,

We have developed an i.mx6dl board which is based on "MX6 Dual Lite SABRE AI CPU2 Card with AVB". I am using version u-boot-2018.01 with SPL.
I am downloading SPL and u-boot.img with USB loader; downloaded kernel and device tree files and run them in nfs tftp search over ethernet..

Then I programmed the SPI NOR flash with u-boot with spi read/write commands for both u-boot.imx/and u-boot.img images with offset value of 0x400 in Flash address, set boot pins accordingly, saw signals at clock, CS and Data pins of flash after reset, but never see a boot (character at terminal) for last few weeks.

As I know, make command is generating code for SD card, and SPL code is waiting u-boot to be loaded from USB port. I searched many NXP/denx forums; i.mx6 linux kernel ref. Manuals for u-boot with SPL, I found NXP supports u-boot.imx images, but did not support SPL+u-boot.img.

So I would be very grateful, if any of you know which (and how) files, parameters (and/or make command) should be set for u-boot.img+SPL boot for SPI nor flash boot in u-boot 2018.1? Or give link to document(s), which explain the i.mx6dl SPL  and u-boot.img boot process for SPI nor flash (except i.mx6 ref manual)..

Thanks and best regards.

Take a look at board/congatec/cgtqmx6eval/README (2. Flashing U-Boot
in the SPI NOR).

It explains how to flash SPL + u-boot.img into SPI NOR on a mx6 board.

Dear Fabio,

Thank you for your helps..

I applied the procedure which is explained in board/congatec/cgtqmx6eval/README document.
Upgraded u-boot to 1018.05-rc1, 
but as you will see below, I received same message;

I will compare my config/header files with congatec's, but I don't know which parameters/definitions (should be /should not be) used; There fore I will appreciate any help if you could..

Thanks and best regards.

You need to debug why you are getting this message when booting from SPI.

Dear Fabio,

I manually set spl_boot_list[]  array with SPI, eMMCx, USB RAM etc. 
For SPI NOR flash loader = spl_ll_find_loader(spl_boot_list[i]) 
function (in spl.c) is returning a negative loader->boot_device number  -442503140

May be there is a definition in u-boot/SPL config files to make file to generate SPI NOR flash boot code, instead of MMC,
Which enable this SPL function to return positive correct value for SPI NOR Flash?

eMMC is working, but I did not put SPL and u-boot in eMMC;
May be you can give me a link explaining how to SPL+u-boot.img to eMMC flash commands.


I added puts() messages to trace the execution;

These are the messages at terminal.

Make sure your board is correctly configured to boot from SPI NOR via
GPIO/fuses.

Dear Fabio

Thank you very much for your directives and helps. 

I applied the steps in WARP board readme file, for the command 

=> ums 0 mmc 2

I received Unknown command 'ums' - try 'help'

I compared with  WARP7 defconfig and mx6sabresd_defconfig files added some definitions in WARP, but got error messages in make file.
Therefore I would appreciate your helps/commends if you write me the definitions in config/defconfig files to enable u-boot to run this command?

Best regads.

[U-Boot] u-boot 2018 SPI SPL

[Mehmet Ali İPİN]

Dear Fabio,

Windows 10 tried but could not load the device driver of our eMMC (micron tech MTFC4GLDDQ). Then

I programmed SPL and u-boot.img into eMMC with u-boot commands; even SPI flash based SPL see the MMC1(eMMC), u-boot did not run correctly.

As shown below, I put printf/puts messages in function entry and exit to debug SPL:

U-Boot SPL 2018.05-rc1 (Apr 27 2018 - 04:15:59 -0700)
SPL set_bd()
SPL Malloc; gd flags
SPL init_i
SPL init_exit
boot mode bmode =32000001
boot mode reg =18080030
SPI serial mode return
board boot order boot list
spl_boot_list:8
spl_boot_list:8
SPL image loader boot device 8
boot device name:MMC1
boot device name:MMC1
boot device name:MMC1
boot device name:MMC1
SPL image loader Not Found
Trying to boot from -442503140
SPL: Unsupported Boot Device!
spl_boot_list:1
SPL image loader boot device 1
boot device name:MMC1
Trying to boot from 1
Trying to boot from MMC1
SPL load image


I disabled #CONFIG_SPL_OS_BOOT=y flag, to disable direct boot linux kernel code, changed boot from SD directives to spi, tested many other serial SPI boot config definitions, included all congatec cgtqmx_defconfig definitions;

İn my SPI SPL, SRC_SBMR1 read returns 0x18080030 which is exactly my spi nor flash register boot setting,  and spl_boot _list:8 (SPI NOR Boot setting, (which is verified by my "SPI serial mode return" printf message), boot device name is always MMC1. Its always trying to boot from -442503140, and can not find SPL image loader finally.. 

Since they did not give all of their u-boot source and config files, It is impossible for me to know how congatec succeded from SPI boot of SPL+u-boot.img,  

But my test of u-boot 2018.01/05 shows, even my DCD header in SPI is correct, even I proceeded congatech's SPI  SPL u-boot.img flash loading sequences, after testing many configurations in 2/3 weeks I am sure there is a problem with SPL u-boot.img for SPI boot such that:

Even on chip ROM code detects correct boot register settings,  jumps to spi flash, starts executing SPL codes, it always search MMC/SD card.

Since it is very important for us to bring this i.mx6 board, which several projects depend on it;

And since I did not see your name in SPL files, May I request your kind helps, if you can direct me to whom developing SPL codes for u-boot 2018 in  list.denx.de group?

Thanks and best regards.

Mehmet Ali Ipin.

I am a bit confused of what you are trying to achieve.

Is your end goal to be able to boot from SPI NOR using SPL on a mx6?

Are you able to boot from SPL from the eMMC or SD card?

Dear Fabio

Thank you very much for your helps.

Yes, my end goal is to be able to boot from SPI flash, with SPL.
We are preparing another PCB to check if we can boot from eMMC/SD.

We received a service proposal from Otavio yesterday, evaluating it.
But if exist, I wish to contact a person who is responsible from SPL in group as well. 

Best regards.

I am a bit confused of what you are trying to achieve.

Is your end goal to be able to boot from SPI NOR using SPL on a mx6?

Are you able to boot from SPL from the eMMC or SD card?

[U-Boot] u-boot 2018 SPI SPL

Dear Fabio,
Hello,

ROM code starts execution of the SPL code in SPI flash; 

I traced and see that It jumped to MMC drivers/mmc.c file,  as default DM_MMC  is not defined, then SPL is calling empty weak "board_mmc_init and cpu_mmc_init" functions. 

I also defined DM_MMC in defconfig file, but got "undefined reference compiling errors for USB etc.

Should I call u-boot MMC init functions within these functions?
Or should I define DM_MMC in config file and try to solve compile errors?

Best regards.
