Hello,
I'm trying to boot the MX6SLLEVK board with SPL, but the SPL build seems to not be included by default in the uboot-imx repo for this processor. Can SPL be used on this processor?
What board should I use as a reference for my build (I am currently using the mx6slevk_spl_defconfig but without success) and what changes do I need to make (OCRAM loading address...)
For now I'm just trying to have a the debug LED setup or a printf in the UART console, so my mx6sllevk_spl.c file is very simple and contains these functions in board_init_f():
- arch_cpu_init()
- ccgr_init()
- setup_debug_led() //muxing and setup of EPDC_VCOM1=HIGH
- setup_iomux_uart() //muxing of UART1 pads
- preloader_console_init()
- printf()
Let me know if you need any more info.
Best,
Vincent
Hi Jeday,
I finally decided to not use a SPL boot but to stick with uboot.imx and start the DDR from there, using the setting from the ddr stress tool.
I used this repo https://source.codeaurora.org/external/imx/uboot-imx/tree/?h=master (be sure to use the master branch, I faced some issues with other branches like lf_v2020.04). You can find some doc for SPL in the doc folder of this repo.
Hope it helps.

Hi Vincent
one can try to follow i.MX Yocto Project User’s Guide sect.5.1 Build configurations select "imx6sllevk".
