I released 5132 even if it is not final.

 

@Jief_Machak

I can't start gdb because of GCC compilation? 

++ '[' 61 -le 60 ']'
++ '[' 61 -ge 60 ']'
++ echo Cannot find '"Clover : Image base = "' in /Users/sergey/src/CloverBootloader/Qemu/serial0_qemu_out.log after 60 seconds
Cannot find "Clover : Image base = " in /Users/sergey/src/CloverBootloader/Qemu/serial0_qemu_out.log after 60 seconds
++ exit 1
iMac2017:CloverBootloader sergey$

And the new bug, type F7 in the GUI

F7 ! Don’t even know what’s it’s for :lol:

Yes I’ll try.

 

for gdb, I think it should look for “CloverX64 : image...” instead of “Clover : Image...”. I’ve updated the scripts recently. Is it the last version ?

I’ll try when I’ll be back home in an hour or so.

I resolved both issue.

1. For F7 there was no empty check.

2. For debug I have to compile with DEBUG_ON_SERIAL_PORT. Else no serial_...log

 

And one more. Returning to missing debug.log.

OC at start rewrite something and then debug log cancels to save.

Our DebugLog(DebugMode, ...) is not same as OC's DEBUG((DebugMode, ...)). There are different flags.

 

Committed.

I did this!

But why ?

Yes you need the serial debug to get the message stating the memory address.

after start, you need the Cliverx64.debug as well as the Cliverx64.efi.

.debug contains all symbols. Efi contains the executable.

best way is to start gdb_launch without any parameters : it’ll get the clover from the build folder.

What is the installation error?

It's because of python. Some support files are missing for python. But we don't need it for Clover debugging.

Script updated. Should work now.

I must admit I always use it with no parameter so gdb_launch go get CloverX64 from "./Build/Clover/DEBUG_GCC53/X64/". Works now with all path, absolute and relative.

I only start OC in StartLoader(). How come OC could write something even before Clover ?

By the way, for information, printing "DBG("CloverX64 : Image base = 0\n");" won't do anything because the address (0 in that case) is wrong and gdb won't be able to break, print stack trace or anything.

By doing that, gdb will still launch and we'll be misled about the origin of the problem.

It is a proof the debug log closed every line and this was not happened before.

both boots was unsuccessful,

Yes, you have to tell me because I thought the last commit wasn't working and the previous WAS working. So maybe the mistake is NOT in the last commit but a bit earlier.

Let's find out.

This : https://github.com/jief666/CloverCommits/blob/master/C-20210328085715-dc17de7.efi, should work. It's the same you confirmed working after you helped me find the problem with KernelPM and KPAppleIntelCPUPM.

If it's working, send me the log so I have a working base to compare to and find what have (wrongly) changed.

If it's working, try the next one here : https://github.com/jief666/CloverCommits and tell me too.
