I want to save the code in flash, but it runs in the internal RAM during runtime. However, I'm not sure how to create the image and burn it. I made an attempt by referring to Processor-specific workflows — Secure Provisioning Tool 26.03, but after the downloader, the device did not start running.
The test environment and steps are as follows. Please help check. Thank you.
Board: MIMXRT1180-EVK
SDK: SDK_26_03_00_MIMXRT1180-EVK
IDE: MCUXpresso IDE v25.6.136
Downloade tool: MCUXpresso Secure Provisioning Tool 26.03
Step1: import evkmimxrt1180_hello_world_cm33 projiect
Step2: Open project Properties > C/C++ Build > Settings > Managed Linker Script and check "Link application to RAM", and change global data placement and “CodeQuickAccess” to DTC_cm33
Step3: Open project Properties > C/C++ Build > MCU settings and ensure that the ITC is the first RAM listed in the available memory areas
step4: change data_init() and bss_init() functions in startup_mimxrt1189_cm33.c code:
step5: Build successfully
step6: Chang board to SDP mode SW5: 0001
step7: Open MCUXpresso Secure Provisioning Tool , choose evkmimxrt1180_hello_world_cm33.axf and bulid image
step8: write image
step9: Chang board to QSPI flash mode SW5: 0100, power-on again.
phenomena: The program is not running properly and no serial port information is being printed. Additionally, using the J-link commander to view the PC pointer, it seems that the PC pointer address points to the HardFault_Handler.
Hi @ethan_dang1,
I noticed that some of the configuration settings you are using differ from the defaults provided in the example.
For example, the location and size of SRAM_ITC_cm33 in the MCU settings, as well as the heap and stack regions in the Managed Linker Script.
Additionally, according to the process, global data placement should be assigned to SRAM_DTC_cm33.
Could you help me by trying the following configuration?
Let me know your results.
Best Regards,
Pablo
