Problem booting using latest linaro-linux-tracking (3.16.0-rc5)/mainline kernel (3.16.0-rc4) on Samsung Arndale Baord

by Mohammad Merajul Islam Molla

Hello, I am having problem booting from latest linaro-linux-tracking (3.16.0-rc5) on Samsung Arndale Board (with two cpus). The same thing happens with mainline kernel (3.16.0-rc4). Here is what happens - 1. During build I got the error message - LD sound/built-in.o MK_FW firmware/edid-1920x1080.fw.gen.S make[1]: *** No rule to make target `firmware/edid-1920x1080.fw', needed by `firmware/edid-1920x1080.fw.gen.o'. Stop. make: *** [firmware] Error 2 I set CONFIG_EXTRA_FIRMWARE="" and could proceed with build. 2. At the end of build I got the below error message - Kernel: arch/arm/boot/zImage is ready multiple (or no) load addresses: This is incompatible with uImages Specify LOADADDR on the commandline to build an uImage make[1]: *** [arch/arm/boot/uImage] Error 1 make: *** [uImage] Error 2 I passed loadaddr as parameter - make uImage LOADADDR=0x40008000 (this address I got from build output of linux-linaro-tracking 3.14.0). With this build was successful and uImage generated. 3. After that I got the following log during boot - [ 1.125626] Trying to unpack rootfs image as initramfs...

[PATCH] Add pinctrl support in powerdebug

by Mohammad Merajul Islam Molla

Add support for pinctrl in powerdebug. Both dump and display modes supported. Tested only on Samsung Arndale board. Sample output in display mode on Arndale Board - Pin Name MUX Owner GPIO Owner HOG Function Group 0 gpa0-0 MUX UNCLAIMED GPIO UNCLAIMED 1 gpa0-1 MUX UNCLAIMED GPIO UNCLAIMED 2 gpa0-2 MUX UNCLAIMED GPIO UNCLAIMED 3 gpa0-3 MUX UNCLAIMED GPIO UNCLAIMED 4 gpa0-4 MUX UNCLAIMED GPIO UNCLAIMED 5 gpa0-5 MUX UNCLAIMED GPIO UNCLAIMED 6 gpa0-6 12c80000.i2c GPIO UNCLAIMED i2c2-bus-mux i2c2-bus-grp 7 gpa0-7 12c80000.i2c GPIO UNCLAIMED i2c2-bus-mux i2c2-bus-grp 8 gpa1-0 MUX UNCLAIMED GPIO UNCLAIMED 9 gpa1-1 MUX UNCLAIMED GPIO UNCLAIMED 10 gpa1-2 12c90000.i2c GPIO UNCLAIMED i2c3-bus-mux i2c3-bus-grp 11 gpa1-3 12c90000.i2c GPIO UNCLAIMED i2c3-bus-mux i2c3-bus-grp --- Android.mk | 2 +- Makefile | 2 +- README | 4 +- display.c | 3 +- display.h | 2 +- pinctrl.c | 329 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ pinctrl.h | 19 ++++ powerdebug.c | 35 +++++-- 8 files changed, 381 insertions(+), 15 deletions(-) create mode 100644 pinctrl.c create mode 100644 pinctrl.h diff --git a/Android.mk b/Android.mk index 36c73cd..19d00ca 100644 --- a/Android.mk +++ b/Android.mk @@ -29,6 +29,6 @@ LOCAL_C_INCLUDES += external/stlport/stlport/ \ LOCAL_SRC_FILES += \ powerdebug.c sensor.c clocks.c regulator.c \ - display.c tree.c utils.c mainloop.c gpio.c + display.c tree.c utils.c mainloop.c gpio.c pinctrl.c include $(BUILD_EXECUTABLE) diff --git a/Makefile b/Makefile index 2da9d67..f002438 100644 --- a/Makefile +++ b/Makefile @@ -5,7 +5,7 @@ CFLAGS?=-O1 -g -Wall -Wshadow CC?=gcc OBJS = powerdebug.o sensor.o clocks.o regulator.o gpio.o \ - display.o tree.o utils.o mainloop.o + display.o tree.o utils.o mainloop.o pinctrl.o default: powerdebug diff --git a/README b/README index 1479db1..b24dd98 100644 --- a/README +++ b/README @@ -1,8 +1,8 @@ powerdebug ---------- -This is a new tool which displays regulator, sensor and clock tree -information. +This is a new tool which displays regulator, sensor, clock tree, gpio and +pinctrl information.
