This article will take MYIR’s MYD-YF13X and STM32MP135F-DK as examples, and continue to explain how to use STM32CubeMX combined with the developer package to implement the booting of the minimal system.



Following "Bring up the STM32MP135x - ST Training Course based on MYD-YF13X (I)"

4.2 USB Boot: FW_CONFIG Configuration and Compilation

In the device tree file generated by STM32CubeMX, there is a config file “stm32mp135d-myir_bring_up-mx-fw-config.dts”, which defines the size of the DDR and contains the “stm32mp13-fw-config.dtsi” file. Once the DDR part of the configuration is completed, this file does not need to be changed and can be compiled directly to generate the “stm32mp135d-myir_bring_up-mx-fw-config.dtb” file, which is loaded into the board by TF-A in the form of a FIP package.

Please read WIKI How_to_configure_TF-A_FIP to learn about the FIP and the commands to generate it.

The FW_CONFIG file compiles:

PC $> cd

PC $> source

PC $> make -f ../Makefile.sdk TF_A_CONFIG=optee TF_A_DEVICETREE=stm32mp135d-myir_bring_up-mx DEPLOYDIR=../../myir_fip/arm-trusted-firmware/ stm32


After successful compilation:



In order to generate the FIP package, the rest of the components still need to be compiled: OP-TEE and U-Boot. We first compile the images of the components based on the nearly empty device tree of OP-TEE and U-Boot generated by STM32CubeMX. Note: Here we just compile a fake OP-TEE & U-Boot image first so that we can package up the FIP and load FW_CONFIG into it.

Compile OPTEE:

PC $> cd < optee-os-stm32mp-3.16.0-stm32mp-r2_path >

PC $> source

PC $> make -f ../Makefile.sdk CFG_EMBED_DTB_SOURCE_FILE=stm32mp135d-myir_bring_up-mx DEPLOYDIR=../../myir_fip/optee/ optee


Three files are generated after compilation, which need to be packaged into the FIP:




Compile U-Boot, and package FIP:

PC $> cd < u-boot-stm32mp-v2021.10-stm32mp-r2_path >

PC $> source

PC $> export FIP_DEPLOYDIR_ROOT=../../myir_fip /*Perform before any stage if requires FIP update*/

PC $> make -f ../Makefile.sdk FIP_CONFIG=optee UBOOT_DEFCONFIG=stm32mp13_defconfig DEVICETREE=stm32mp135d-myir_bring_up-mx DEPLOYDIR=../../myir_fip/u-boot/ all


Compile successfully and obtain:




Burn the generated FIP file to the board via USB and STM32CubeProgrammer. Test FW_CONFIG:

PC $> cd ../../myir_fip

PC $> STM32_Programmer_CLI -c port=usb1 -c port=usb1 -d arm-trusted-firmware/tf-a-stm32mp135d-myir_bring_up-mx-usb.stm32 0x1 -s 0x1 -d fip/fip-stm32mp135d-myir_bring_up-mx-optee.bin 0x3 -s 0x3


The serial port log after burning is as follows.

In the previous step, the serial port log stopped at:

"

INFO:    handle USB : Suspend int

INFO:    USB Suspend mode

INFO:    handle USB : Reset

"

Stuck at further load FIP, FW_CONFIG. In this section, FW_CONFIG has been packed into the FIP and burned into the board, the serial port outputs more information, please check the highlight section, and eventually stops at the OP-TEE stage, and the Error Reporting section is also highlighted. Note: if the serial output is with "x/TC", it proves that it has already jumped to OP-TEE running, for example:

“

PANIC at PC : 0x2ffe7a87

Exception mode=0x00000016 at: 0x2ffe7a87


PANIC appears after load image id 1, please note the difference between the design of the MYIR board and the STM32MP135F-DK: in addition to the different design of the power supply part, there is also a different selection of chips. MYIR uses the stm32mp135d series, while the demo board uses the stm32mp135f series. The difference between the two series is whether or not to include SAES, PKA, etc., secure IP and whether or not the DDRMCE attributes. MCE is enabled by default on the F series, and the FW_CONFIG file defines the area for DDR encryption, which needs to be configured by invoking MCE. The encryption process will use the RNG module, so the configuration of MCE, firewall need to enable the RNG in the TFA phase.


After enabling RNG, recompiling TFA, Deploy TF-A and FIP, the serial port output is as follows ( same as MYIR output):
