Trying to clear boot sequence from errors while building mainline version with following parameters:
KERNEL_ONLY="no"
KERNEL_CONFIGURE="no"
CLEAN_LEVEL="make,debs,oldcache,images"
DEST_LANG="en_US.UTF-8"
BOARD="pine64so"
BRANCH="next"
RELEASE="xenial"
BUILD_DESKTOP="yes"
KERNEL_KEEP_CONFIG="no" # do not overwrite kernel config before compilation
EXTERNAL="no" # build and install extra applications and drivers
EXTERNAL_NEW="prebuilt" # compile and install or install prebuilt additional packages
CREATE_PATCHES="no" # wait that you make changes to uboot and kernel source and creates patches
BUILD_ALL="no"
I get following error:
sunxi-de2-clks 1000000.clock: Error couldn't map SRAM to device
This is message is generated in ccu-sun8i-de2.c line 252 as sunxi_sram_claim() returns -EPROBE_DEFER, which is <0, but not an errorr, as it ask the system to try again after that global variable static void __iomem *base has been set - a typical legal side effect with DT being probed with random order.
Actually system tries again later and that time is successful - no error.
I suggest that the error clause is changed to
if (ret && (ret != -EPROBE_DEFER)) {
dev_err(&pdev->dev,
"Error couldn't map SRAM to device\n");
return ret;
or a warning message sent in case of -EPROBE_DEFER value.
Attached a patch file for that problem; As I am pretty young to Linux kernels, please double check if it will not generate other side effect with different HW or standards
ww-C-sunxi_de2_cloc_non-error_removed.patch.
