a couple years ago to build RTEMS for the Arty and things may have changed. I don't know much about the RED-V board, but it might be worth investigating the need for a bootloader.hex file for the board. I think, at least on the Arty, RTEMS relies on the
bootloader and dtb to be set up the environment before taking over. I don't know if the bootloader Pragnesh provided is compatible with your board or not, but it is probably worth looking into.

<b>Subject:</b> RTEMS for RED-V board</font>
<div> </div>
</div>
<div>
<div dir="ltr">Hi,
<div><br>
I've just bought a RED-V board (<a href="https://www.sparkfun.com/products/15594" target="_blank">https://www.sparkfun.com/products/15594</a>) based on a SiFive FE310 SoC. I've successfully tested a bare-metal (with FreedomStudio) and a Zephyr program on it. When connecting
the board to USB a folder appears and you just have to copy a .hex file to flash the board :-)</div>
<div><br>
</div>
<div>I've tried RTEMS (5.1) with frdme310arty BSP (contributed by Pragnesh Patel from SiFive) but it looks like the hex file is not recognized. I've created the hex file with "riscv-rtems5-objcopy -O ihex helloworld.exe helloworld.hex".</div>
<div><br>
</div>
<div>I know the boards are different as both are supported by FreedomStudio and there are some differences in the dts files (freedom-e310-arty vs sifive-hifive1-revb BSP).</div>
<div><br>
</div>
<div>Any idea ?</div>
<div></div>
<div><br>
</div>
<div>thx by advance</div>
