What are the differences u-boot 2009 and 2014?

mehmetipin — Mon, 09 Jan 2017 05:48:04 GMT

Dear community,

We have a custom MXDL prototype board, which u-boot 2009 is being downloaded, but for 2014, I receive the following messages. I used flash_header.S in 2009, since I could not find it in 2014, instead I carried register settings of flash_header into mx6dlsabres.cfg file.

I could not set the DCD section of 2014, which is for sabresd board, not for my board; Any one knows the name of the file which I can set the DCD of 2014 accordingly?

Best regards.

Dear Yuri,

Thank you for your informations. I have already read the document "imx bsp porting guide.pdf, paragraph 1.3.1", ported ddr_stress_test register settings to mx6dlsabres.cfg file, same as in flash_header.S for u-boot 2009 (it is already working), but for u-boot 2015, I am receiving the messages above.

Would you please have a look it, What are the meaning of "vid=0x066f pid=0x3780 file_name=mx23_usb_work.conf" ?

Do these message show us DDR is initialized?

Best regards.

Hello,

You should use u-boot.imx.

u-boot.bin and u-boot.imx
