How to configure uboot on 2080RDB to boot a PCIe Video Card?

[robertoinnocent]

We need to install debian linux for desktop on 2080RDB devkit so we need to change uboot config to boot a PCIe Video Card ( ATI) . How we can confiugure uboot?

Hello thank you very much for the answer Roberto,

I will take a look to these threads ASAP. I hope I make similar configurations to my t1042 system.

Hello ,robertoinnocenti‌

Can you explain these steps ? I am trying to do something similar, using a GPU over PCI express with t1042 for U-boot console messages.

If SDK-2.0-1703 is used apply the following patch to fix it:

http://git.freescale.com/git/cgit.cgi/yocto/meta-nxp-npi.git/commit/?h=jethro-sdk-v2.0-ga-17.03

Attached file contains corrected linux-qoriq_4.1.bbappend file. Path for this file is the following:

/QorIQ-SDK-V2.0-20160527-yocto/sources/meta-nxp-npi-1703/recipes-kernel/linux$ ls

linux-qoriq_4.1.bbappend

Have a great day,

Thank you; now I have recompiled the kernel image.

The u-boot I have in the T2080RDB is already compiled with ?

#define CONFIG_BIOSEMU                  /* x86 bios emulator for vga bios */ #define CONFIG_ATI_RADEON_FB            /* use radeon framebuffer driver */

[Pavel]

U-boot supports console as terminal. It does not support video cards. U-boot usually does not initialize PCIe cards.

It does not have code for PCIe card operations.

NXP offers SDK 2.0 for LS2080ARDB board:

http://www.nxp.com/products/software-and-tools/run-time-software/linux-sdk/linux-sdk-for-qoriq-proce...

This SDK supports PCIe.

Check drivers for your card in kernel menu:

   Device Drivers  --->    

        Graphics support  ---> 

           Frame buffer Devices  ---> 

Use the following command sequence for kernel menu:

• If kernel source code is not installed, install kernel source code first.

bitbake -c cleansstate virtual/kernel

bitbake -c patch virtual/kernel

bitbake -c menuconfig virtual/kernel

Rebuild kernel using the following command:

bitbake virtual/kernel

So now I'm Customizing U-Boot to support ATI video cards

Get uboot source:

bitbake -c cleansstate u-boot

bitbake -c patch u-boot

Go inside a uboot source folder:

cd build_t2080rdb-64b/tmp/work/t2080rdb_64b-fsl-linux/u-boot-qoriq/2016.09+fslgit-r0/git/include/configs

I have modified include/configs/T208xRDB.h

with

+/* Video */
+#define CONFIG_VIDEO
+#define VIDEO_IO_OFFSET

+/* Video */
+#if defined(CONFIG_VIDEO)
+#define CONFIG_BIOSEMU
+#define CONFIG_CFB_CONSOLE
+#define CONFIG_VIDEO_SW_CURSOR
+#define CONFIG_VGA_AS_SINGLE_DEVICE
+#define CONFIG_ATI_RADEON_FB
+#define CONFIG_VIDEO_LOGO
+#endif

I have tried to compile uboot:

• cd build_<machine>
• $ bitbake -c compile -f u-boot

but with errors:

../drivers/bios_emulator/besys.c: In function 'BE_inb':
| ../arch/powerpc/include/asm/io.h:50:42: error: expected expression before ')' token
|  #define inb(port)       in_8((u8 *)((port)+_IO_BASE))

Done successfully:
bitbake -c cleansstate virtual/kernel
bitbake -c patch virtual/kernel

doing command:
bitbake -c menuconfig virtual/kernel

Exit with ERROR:

Thank you, I have forwarded your answer to the person of our team that is working with uboot, I will update about the evolution
