Hi Fabio, Peng, and all. I just ran into a problem with bus frequency switching on the EVK and there appears to be a U-Boot component.
Using the 4.1.15 kernel from git.freescale.com (commit a4d2a08) and the latest U-Boot from Stefano's imx tree (commit a3e5519) causes the EVK to hang during a bus frequency switch to LOW_POWER mode. The last gasp is this: Bus freq set to 24000000 start... And the code block in question is here: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/mach-imx/busfreq_ddr3.c?h=imx_4.1.15_1.0.0_ga#n386 When using the binary U-Boot 2015.07 from the EVK package (commit d7d7c43 from git.freescale.com), the kernel gets through the frequency switch and produces this message. Bus freq set to 24000000 done! I first saw this problem with u-boot-fslc branch v2016.07 and linux-fslc (4.1.29 and 4.1.30). Has anybody else experienced this?
