Cooperate with rust code

[ducdracaena]

I wrote the firmware in rust code with read function, I tried to run this program in Naxriscv but stuck in read function.

Another side, I tried that function in vexriscv ,this worked fine!

This is the firmware:
unsafe fn main() -> ! {
// led debug
let LED_ADDR: u32 = 0x10000000;//0x10000000 with vexrisc and 0xFF000000 with naxrisc
let mut led: u32 = 0x00000000;
//let mut tcp_status;

// TCP interface
//let TCP_STATUS_ADDR: u32 = 0xFF000000;
//let TCP_RX_ADDR: u32 = 0xff000020;
//let TCP_TX_ADDR: u32 = 0xff000030;

// init led
(LED_ADDR as *mut u32).write_volatile(led);
loop {
   led = (LED_ADDR as *mut u32).read();
   
   led = led ^ 0xFFFF000;
    (LED_ADDR as *mut u32).write_volatile(led);
    
    delay(100);
}

}

Can you please check that?

Thank you,

Hi,

So far, what i tested with rust was compiling and running it in NaxRiscv debian.
Seems it was going well.

Could you provide a way to reproduce your issue ?
binaries i could run using that simulation environnement :
https://github.com/SpinalHDL/NaxRiscv/tree/main/src/test/cpp/naxriscv

or a wave of your simulation.

Hello,

Can you please try this 2 files:

Hi,

Do you need anymore information or elf or vcd file?

Thank you,

Hi ^^

So, the https://file.io/tK8EdXJSbwoD files are deleted.
I need the wave and the elf :)

Thanks

Hi,
Seems like your issue is comming from the peripheral / interconnect side of things.
See :

Getting an AXIlite r response with zero latency isn't something AXIlite compatible. (and it confuse NaxRiscv).

Seems like the issue is between :
the outputs of cpu_LsuPeripheralAxiLite4_logic_axi_readOnlyDecoder
->
peripheral_axil
