linkserver loading binary

yosri_c — Tue, 08 Jul 2025 09:29:44 GMT

Greetings NXP support

we're trying to automate our boards set up (imx RT1176) , and we are using Linkserver cmd with MCU_LINK in a python script to flash and load binaries in Flash NOR , and we are using a minimal Flashloader to burn couple of fuses and for some specific hw initialization , for the moment we are done with loading binaries in Flash , but we couldn't figure out how to load and run flashloader into OCRAM1 using linkserver

C:/nxp/LinkServer_24.12.21/LinkServer.exe flash MIMXRT1176:MIMXRT1170-EVK load combined_RAW_image.bin:0x60000000 ( this is for flash NOR )

anything might help ?

Kind regards

Hello!

To load and run your minimal Flashloader into OCRAM1 on the i.MX RT1176 using LinkServer, you'll need a two-step process instead of your current flash command. First, use LinkServer.exe flash MIMXRT1176:MIMXRT1170-EVK load your_flashloader.bin:0x20200000 to transfer the binary to OCRAM1 (confirming the exact address). Then, execute it with LinkServer.exe flash MIMXRT1176:MIMXRT1170-EVK go 0x20200000. Ensure your flashloader binary is designed for direct execution from RAM.

i think this command would try to load the binary into flash not ram ..

Hi @yosri_c ,

This project maybe helpful for you: https://www.nxpic.org.cn/module/forum/thread-620172-1-1.html

It makes the flashloader as a bin array and loads it into RAM and jumps in the main function.That is, this program can be applied to any debugger.

Best regards,
Gavin
