Hi austin, hi aignacio
I post in this thread since I think I'm stuck in a similar situation and I hope someone of you can help me.
I have a cyclone V de0 nano soc board and I want to boot a bare metal application from SD card.
This is what I could do so far:
- I built a working baremetal application and I can debug via jtag
- I created the u-boot.scr script file to load fpga configuration and baremetal application
- I copied the .scr on SD card and it get executed, as I can see in the serial port output log
- during the boot process, FPGA can successfullly configure from the .rbf file I copied in the FAT partition of SD card
- when the script tries to load the application (fatload mmc 0:1 0x00100040 app_image.bin) I clearly get an error, since I still don't have the app_image.bin which is supposed to contain my application.
The point is that I don't understand how to generate it from the .axf file I get from the build tools!
I read this and other threads and I believe I simply need this .bin file on the SD card
I used objcopy as someone suggested, but this creates a 4GB file! Moreover mkimage then tells me it can't read it.
I'm missing some point?

Hello Cris72,
to generate the .bin file you'll need to use this command after generate your .axf:
arm-altera-eabi-objcopy -o binary baremetal.axf baremetal.bin Also as I was stucked in this generation steps, I decided to make a big tutorial for my blog to explain all the process after understand the required files to generate a bootable SD card. As my post is not complete yet I'll paste here a preview that's only accessible through this link (
https://blog.aignacio.com/p/b0ed896e-9982-4b40-a3e9-cc8cabea31ff/), try to read my tutorial and check if this could help you through the steps and if you find any error just reply. :)
