I think you should check more detail in section 12 "Standard Boot Strategies". It needs more things to do.

As the code execute on NOR flash, so, the SPL configure the CPU clock will cause SMC access abortion. So, a brief guide as following: 1. Write a ram function, which do as the datasheet says. 2. Add copy function (copy the ram function into sram) at the begin of the SPL code. 3. After the step 1, finished to execute, then, you can jump back to NOR to execute. May you got what I mean, if any questions, please let me know. > Many thanks, > > Andy. Best Regards, Bo Shen

[U-Boot] strtonum() is gawk specific extension
by Vasili Galka 18 Jun '14

18 Jun '14

The following patch "Check that u-boot.bin size looks correct": http://patchwork.ozlabs.org/patch/355151/ Uses strtonum() function which is gawk specific extension: https://www.gnu.org/software/gawk/manual/html_node/Strtonum-Function.html As a result, currenlty, u-boot/master generates build errors on systems with alternative awk implementations e.g. I get: awk: line 2: function strtonum never defined Either gawk shall be required and explicitly used or the implementation changed. Best, Vasili

[U-Boot] Use UART1 port on p1022 through U-Boot
by Nildo Junior 18 Jun '14

18 Jun '14

Hi, I am using a Freescale p1022 processor, and I need to write to the UART1 port of this processor, through U-Boot. I know it currently uses UART0 as the console input/output. I could not find out how to configure it so I can use UART1 as well. If somebody have a hint, I will be really grateful. Cheers, Nildo Junior

[U-Boot] [PATCH] dfu: free entities when parsing fails
by Stephen Warren 18 Jun '14

18 Jun '14

From: Stephen Warren <swarren(a)nvidia.com> When dfu_init_env_entities() fails part-way through, some entities may have been added to dfu_list. These are only removed by dfu_free_entities(). If that function isn't called, those stale entities will still exist the next time dfu_init_env_entities() is called, leading to confusion. Fix do_dfu() to ensure that dfu_free_entities() is always called, to avoid this confusion.
