migrating from krikstone to mickledore unable to flash via DFU panic halt

Dear STM comunity, 
i am currently trying migrate my solution from the kirkstone to  mickledore because it offers more software functions that i need and cant properly use on the kirkstone, 

i have spent alot of time trying to port the configurations from OSD32MP1F to mickledore via cube mx, here are the device tree, there are alot of differences between versions but overall nothing too diffrent, i managed to compile the image and started flashing , however i don't know what are the issues but i am not able to flash the image due to a panic error leading to flashing halt as shown in the LOG 1 and LOG2

LOG2 : Print of uart 4 connected via serial coomunication using cutecom during flashing 
as seen in LOG2 there is a panic during the flashing process, i was trying to blindly modfiy the device tree on the optee half and tfa while following the examples on the EV1 DT board and while adding my rcc and source code from the Cubemx generated code but no luck. i dont know why its paniking , i can not use GDB to further debug. 
here is my board config text as seen in scrc1 and src2 .

could you please dear ST comunity help me figure this thing out i am really out of leads , i don't know if i need to share the device treers ? or maybe help me get the location where there is an issue

Thank you

Hello MScor.1, indeed your thoughts are correct its not a regulator issue , i have managed to get everything working after extensive research and understanding to every single device tree node, and the working of the boot chain .... 
for my case it was an issue of etzpc and memory , i was relying on the files generated with the cubemx however some key changes are crusial to get this working, increasing the debug level indeed contrebuted greatly to find the issue. 
for my case , it was not an uboot problem , it was an optee device tree configuration as i said. this exact bug i had to make sure to specify the "secure-status = "okay"; " on the nodes that they are going to use an unlcok through the trustzone firewall.

@iheb 

Try to enable debug level = 4 and set DEBUG=y on Optee first. Do that in the Makefile of Optee.

thank you for the reply , after seting the optee debug level to 4 

here iis the resulting log , i have meraculasly found out that the first log is a watchdog issue , the error changed when i changed to watchdog1 like the examples.

at this point i have no idea what could be wrong with the device tree as the error points out that there is somehting in the device tree drivers in line 147 to 153

1. You're missing regulators

2. You don't specify the voltage for the processor.

 

Here copy these instead.

This will solve your problem :) @iheb

I am not sure missing regulators are the issue.

I have the same problem on mickledore, using the DK1 and I have the PMIC regulators in place for vddcore and vdd, with voltages specified.

The person in this post seems to have the same symptom, and they also seem to have regulators in place: they are on a custom board without PMIC, but they have fixed-regulator nodes that make sense.

I also tried the `reserve-memory` change from this post, with no change.

I have been struggling with this for a couple of days and at this point I am running out of options, so an ST employee chiming in might help, @Amel NASRI @Olivier GALLIEN (sorry for the direct mention, you seem to be the ST employees that interact with MPU forums and have the most posts).

I have attached my latest u-boot dts that shows the error even with the reserve-memory change. 

EDIT: I have now also attached an optee log with debug level=3. Note that in this optee.log file I had replaced the PMIC config with fixed regulators, following advice from Lab-MP15_FromPartNumber_To_BasicDeviceTree_with_CubeMx.pdf available here)

Well, ST is famous for not bug testing their code, @MScor.1 

I think the best option is to compile everything from pure source code. I mean, clone the repositories from GitHub and compile them with make.

Then you will not having these mysterious behavior.

Hello MScor.1, indeed your thoughts are correct its not a regulator issue , i have managed to get everything working after extensive research and understanding to every single device tree node, and the working of the boot chain .... 
for my case it was an issue of etzpc and memory , i was relying on the files generated with the cubemx however some key changes are crusial to get this working, increasing the debug level indeed contrebuted greatly to find the issue. 
for my case , it was not an uboot problem , it was an optee device tree configuration as i said. this exact bug i had to make sure to specify the "secure-status = "okay"; " on the nodes that they are going to use an unlcok through the trustzone firewall.

from the log that you provided , i think its a watchdog device tree declaration issue, make sure to use watchdog 1 for optee and tfa , and watchdog 2 for the uboot and the linux kernel

I see this post is marked as a solution, but... I am not sure it is. 

According to the kernel documentation, the "secure-status" property defaults to the the same value as the "status" property, i.e. if a device is enabled with "status=okay" it is already available in both the secure and non-secure domains. Of course I might be wrong, but I think that means that adding "secure-status = "okay"" should make no difference, unless you explicitly disabled a peripheral in the non-secure domain. 

Which nodes did you have to apply this to? Are you sure you didn't change something else at the same time?

unfortunately I am already using wdg1 for optee/tfa, and no wdg for u-boot and the linux kernel, so I think it's something else.

In my logs you do see the watchdog kicking in, but I think it's because it's doing its job: optee got stuck before jumping to u-boot, and after a while the wdg reset the MPU.
