*HI, *
*OS:* petalinux <https://github.com/Xilinx/u-boot-xlnx/tree/master-next> *Board:* Xilinx z702 evaluation board<http://www.xilinx.com/products/boards-and-kits/EK-Z7-ZC702-G.htm> having ARM Cortex A9 and FPGA on the zc700 SoC * Background:* I observed that first message on the console comes after 1 second. It is the message from u-boot. Why this was happening? Because I had to use a fsbl (first stage boot loader)<http://blog.fakultaet-technik.de/development-with-zynq-part-3-build-boot-files/> for initialization of hardware. I suspected that it is this fsbl that is consuming 1 second initializing useless hardware which I will not use at all. in fact I am not going to use any fpga bitstream also. So I am trying to boot my Linux image using uboot-SPL method<http://www.denx.de/en/pub/Documents/Presentations/EWC2012_Roeder_Zundel_Fastboot.pdf> bypassing fsbl. The main advantage I can get is perhaps fastest possible boot. I found this<https://github.com/Xilinx/u-boot-xlnx/blob/master/doc/README.SPL> (README.SPL) document that explains how to work with SPL. However I have following question w.r.t to the this passage in the document: The building of SPL images can be with: define CONFIG_SPL Because SPL images normally have a different text base, one has to be configured by defining CONFIG_SPL_TEXT_BASE. The linker script has to be defined with CONFIG_SPL_LDSCRIPT. Questions: 1- In which file I should define #define CONFIG_SPL and CONFIG_SPL_TEXT_BASE? 2-Where is the linker script? Do I need to define CONFIG_SPL_LDSCRIPT in the linker script ? Source code of SPL enabled u-boot for xilinx board I am using is this<https://github.com/Xilinx/u-boot-xlnx/tree/master-next> This is the first time I am trying to play with SPL so kindly help me proceed. Thanks and regards, HB
