Recovery doesn't have some functions

lqll — Fri, 04 Dec 2015 07:55:03 GMT

My environment is i.MX6Q and Android4.4.2 1.0.0-rc3

I want to modify update.zip to support update uboot,and I follow Android_Frequently_Asked_Questions.pdf 's section How do I customize the reference OTA application

I added this command to the end of updater-script

# Write u-boot to 1K position.

# u-boot binary should be a no padding uboot!

# For eMMC(iNand) device, needs to unlock boot partition.

ui_print("writting u-boot...");

package_extract_file("files/u-boot-6q.bin", "/tmp/u-boot-no-padding.bin");

sysfs_file_write("class/mmc_host/mmc0/mmc0:0001/boot_config", "1");

simple_dd("/tmp/u-boot-no-padding.bin", "/dev/block/mmcblk0", 1024);

sysfs_file_write("class/mmc_host/mmc0/mmc0:0001/boot_config", "8");

show_progress(0.1, 5);

When I enter recovery mode,I failed and get this log:

Finding update package...

I:Update location: /cache/update.zip

line 91 col 67: unknown function "sysfs_file_write"

3 parse errors

E:Error in /cache/update.zip

(Status 6)

Installation aborted.

It said I didn't have some functions.Then I check what functions do I have in recovery,I get this:

./edify/expr.c: RegisterFunction("ifelse", IfElseFn);

./edify/expr.c: RegisterFunction("abort", AbortFn);

./edify/expr.c: RegisterFunction("assert", AssertFn);

./edify/expr.c: RegisterFunction("concat", ConcatFn);

./edify/expr.c: RegisterFunction("is_substring", SubstringFn);

./edify/expr.c: RegisterFunction("stdout", StdoutFn);

./edify/expr.c: RegisterFunction("sleep", SleepFn);

./edify/expr.c: RegisterFunction("less_than_int", LessThanIntFn);

./edify/expr.c: RegisterFunction("greater_than_int", GreaterThanIntFn);

./updater/install.c: RegisterFunction("mount", MountFn);

./updater/install.c: RegisterFunction("is_mounted", IsMountedFn);

./updater/install.c: RegisterFunction("unmount", UnmountFn);

./updater/install.c: RegisterFunction("format", FormatFn);

./updater/install.c: RegisterFunction("show_progress", ShowProgressFn);

./updater/install.c: RegisterFunction("set_progress", SetProgressFn);

./updater/install.c: RegisterFunction("delete", DeleteFn);

./updater/install.c: RegisterFunction("delete_recursive", DeleteFn);

./updater/install.c: RegisterFunction("package_extract_dir", PackageExtractDirFn);

./updater/install.c: RegisterFunction("package_extract_file", PackageExtractFileFn);

./updater/install.c: RegisterFunction("symlink", SymlinkFn);

./updater/install.c: RegisterFunction("set_perm", SetPermFn);

./updater/install.c: RegisterFunction("set_perm_recursive", SetPermFn);

./updater/install.c: RegisterFunction("set_metadata", SetMetadataFn);

./updater/install.c: RegisterFunction("set_metadata_recursive", SetMetadataFn);

./updater/install.c: RegisterFunction("getprop", GetPropFn);

./updater/install.c: RegisterFunction("file_getprop", FileGetPropFn);

./updater/install.c: RegisterFunction("write_raw_image", WriteRawImageFn);

./updater/install.c: RegisterFunction("apply_patch", ApplyPatchFn);

./updater/install.c: RegisterFunction("apply_patch_check", ApplyPatchCheckFn);

./updater/install.c: RegisterFunction("apply_patch_space", ApplyPatchSpaceFn);

./updater/install.c: RegisterFunction("read_file", ReadFileFn);

./updater/install.c: RegisterFunction("sha1_check", Sha1CheckFn);

./updater/install.c: RegisterFunction("rename", RenameFn);

./updater/install.c: RegisterFunction("wipe_cache", WipeCacheFn);

./updater/install.c: RegisterFunction("ui_print", UIPrintFn);

./updater/install.c: RegisterFunction("run_program", RunProgramFn);

and there are no sysfs_file_write and simple_dd,then I check the recovery's git log,I get this:

Do I have the wrong version?

Hi,

You can find the simple_dd function here:

t80_platform_bootable/install.c at master · onyx-intl/t80_platform_bootable · GitHub

Same for the sysfs write:

t80_platform_bootable/install.c at master · onyx-intl/t80_platform_bootable · GitHub

Hope this helps.

Regards,

Gary
