Bdm functions

Depending on the target part, the BDM controller may feature a hardware breakpoint register. The register holds a value indicating an address in memory. When the target part’s CPU accesses that location in memory, the BDM hardware can take control of the target part, stop program execution, and begin operating in background mode.

Here you can find all secret codes for HUAWEI P30. Check out how to enter hidden mode and use advanced options of Android 9.0 Pie. Let’s get access to secret information about HUAWEI P30. Click here and find out more information about secret codes.

IMEI
*#06#
Calendar
*#*#225#*#*
FCM Diagnostics
*#*#426#*#*
About Phone
*#*#0000#*#*
Project Menu
*#*#2846579#*#*

To see your IMEI you need to open Phone dialer and type in *#06#. You should see the 15-dight IMEI Number.
Begin by opening the Phone dialer app and then type in *#*#225#*#. As you can see Calendar shows up on the screen. This menu helps you to check important dates like holidays, birthdays and more.
To open FCM Diagnostic menu, enter *#*#426#*#*. Here you can check information about a connection with the server and connected network.
If you would like to get access to the advanced settings of your HUAWEI P30 to, for example, Developer Options, then put *#*#0000#*#*, where you will be able to find Model, Build Number, Hardware version, IMEI1, IMEI2, MSPL version, MLPL version, ICCID.
Let’s type *#*#2846579#*#* to open to the Project Menu in order to get access to the Background Setting, Veneer Informations, Network Informations Query, Software Upgrade, Restore Factory, Battery Charge.
- Background Settings – Here, you can enter Background Debug, USB Port Settings, and AP LOG Settings.
- Veneer Informations – At this moment you can find out Version Info, Manufacture Info, Other Info, and Verify Key.
- Network Information Query – Now, you are able to check PLMN Info, SIM Lock Info, Fuse Info, and Vendor Country Info.

I/o signals

The signals used by BDM to communicate data to and from the target are initiated by the host processor. The host negates the transmission line, and then either

At the start of the next bit time, the host negates the transmission line, and the process repeats. Each bit is communicated in this manner.

In other words, the increasing complexity of today’s software and hardware designs is leading to some fresh approaches to debugging. Silicon manufacturers offer more and more on-chip debugging features for emulation of new processors.

This capability, implemented in various processors under such names as background debug mode (BDM), JTAG and on-chip in-circuit emulation, puts basic debugging functions on the chip itself. With a BDM (1 wire interface) or JTAG (standard JTAG) debug port, you control and monitor the microcontroller solely through the stable on-chip debugging services.
