Please provide the details of the SD configuration used and the board schematics. Report any XSCT error. In order to determine this, use an image with FSBL debug prints enabled. Try to do a brief investigation before filing a Service Request.

Use the u-boot. A debug option could be to limit the SD interface speed to "standard" 25MHz and see if the error persists. Please provide the log of the mmc commands to exercise the SD using pre-built u-boot image from the wiki. Specify the u-boot version used. Some Debugging is required to understand where the example is failing through the SDK debugger or by adding debug prints.

If you assume the card has timing issues you can slow down the clock in Linux to 25MHz using the following device tree node:. Xilinx - Adaptable. Description Solution Attachments. Solution Before opening a Service Request, collect all of the information requested below. See UG chapter 11 and Xilinx Answer An easy way to provide this register dump is to use the attached. Report the type of failure in the Xilinx stand-alone example.

Users will need to connect to the target and set the symbol file for the program running on the target. This method can also be used to debug Linux kernel booting from flash.

For best results, the code running on the target should be compiled with debug info. Users must clear resets on each core, before debugging on these cores.

Comments begin with. While a program is running on A9 0users can download another elf onto A9 1 and debug it, using similar steps. Users can just select A9 1 target and download the elf and continue with further debug.

To run the program in previous example using a script, create a Tcl script and name it as, for example, test. The script can be run by passing it as a launch argument to xsdb. You can create Tcl scripts with XSCT commands and run them in an interactive or non-interactive mode.

In the interactive mode, you can source the script at XSCT prompt. For example:. In the non-interactive mode, you can run the script by specifying the script as a launch argument. Arguments to the script can follow the script name. The script below provides a usage example of XSCT. These commands can be either scripted or run interactively. After the execution, launch the Vitis development environment and select the workspace created using XSCT, to view the updates.

For MB designs, the uartlite driver can be used. Create a FSBL application thereafter.

Note: Creating an application project creates a BSP project by adding the necessary libraries. Note: Assuming the board to be zc Below is an example of debugging a program already running on the target. For demo purpose, the program has been stopped at mainbefore this example session. The flow described here can be applied to other boot modes too, with minor changes.

Note: Similar steps can be used for debugging applications on R5 cores and also on A53 cores in 32 bit mode. However, the A53 cores must be put in 32 bit mode, before debugging the applications.

This should be done after POR and before the A53 resets are cleared. Note: If the. Note: When the BSP settings are changed, it is necessary to update the mss and regenerate the BSP sources to reflect the changes in the source file before compiling. The targets are assigned IDs as they are discovered on the Jtag chain, so the IDs can change from session to session.

Default is zcu b.Every statement using the function is then printed in the serial output. Launching the PMU Firmware see the previous blog entry here displays additional statements in the serial output that might help us to understand the execution flow. The PMU Firmware core code also provides an additional logging mechanismand functions that can be used for further debugging.

The console output shows how the nodes that have not been assigned to any master disabled peripherals in the Vivado design have been powered-off once the PMU Firmware gets the configuration object from the FSBL. Using the serial log is a common debugging technique and although it is widely used, it might be not the best approach for some cases adding additional log statements requires additional compilations.

Debugging the code with a debugger provides much more visibility as it allows you to debug through the code while having access to the different symbols and memory during the application execution. These options can be removed, but that implies that the code will grow in size and as per Table in UG there is not a lot of space available in the PMU RAM memory to allow for this.

The solution is to minimize the optimization level as much as possible while disabling the serial log options in order to save as much space as possible, without disabling any other functionality within the PMU Firmware. To get the best debugging experience, compile the PMU Firmware with the -Og level and -finlinefunctions-called-one option as per the below image. If the PMU Firmware requires additional modules to be enabled and there is not enough in the memory for the build, use additional optimization options in the build as documented in the GCC documentation.

The above configuration settings allow us to set breakpoints and debug through the PMU Firmware code in a seamless way using the Xilinx System debugger.

The following image shows a debug session screenshot with a debug session launched from SDK. Up to now the PMU Firmware has been loaded using the debugger, but sometimes debugging a real boot process might be required for example, a boot image loading from the SD interface. Xilinx SDK provides a way to launch a debug session configured as "Attach to running target".

This allows you to just connect to a target and run a custom script. When debugging the boot process with the PMU Firmware, there are some important considerations that can that make the debug process more complex than with other use cases, but with the help of a script it can be automated, providing a seamless debug experience.

On the one hand, the PMU processor is not accessible from the TAP by default; a gate prevents the access so this needs to be enabled by writing to the corresponding register within the PS. On the other hand the debug symbol file cannot be mapped before the PMU Firmware is loaded in the device, which means the debugger needs to detect this event to map the file afterwards.

As an example, let's see how to debug a boot image placed in an SD card that has been created using the following BIF file. When the debug configuration is launched on a running target, the device has already been booted, so the first step required to debug the boot process is to reset the system. The PMU Firmware debug symbol cannot be loaded into the target until the firmware is loaded in the processor, so the debugger needs to monitor the target to detect this event.

Finally, in order to debug an application with source code visibility, the symbol file needs to be provided to the debugger. The following commands have been included in the script to map the symbol file and place a couple of breakpoints based on function names.

In addition to these breakpoints, you can also place breakpoints using the source code window or the breakpoint window, but be aware that these need to be placed every debug session every time a new debug is launched.
