Firmware / Re: Maybe bricked the firmware on my Blackbird

« on: April 05, 2025, 08:49:13 pm »

The flash chip needs to be configured to enable hardware write protection. It defaults to not enabled. So, even with the DIP switches set to disable writes it's still possible to write to the flash chip.
I don't know if the BMC firmware does or can even change that setting.

The write protect needs to be enabled in firmware which defies the whole point of hardware write protection.

Yes, you should be able to flash the PNOR chip (I've never tried it though).
It's the BMC chip that needs to be flashed prior if it's blank/corrupted.

If the PNOR IC is dead you can buy one from a site like mouser or digi-key [PNOR] [BMC].

Compiler explorer is a cool tool, not sure if it has the features you're looking for though.

I just opened up an old Cisco Wifi AP I had stashed away. It has an AMCC PPC405EP processor.

For the llama3.2, CPU only, on my blackbird (4-core, 32GB) I get 5.94 tokens/s but on my TalosII (18-core, 368GB) I only get 0.34 tokens/s

Thanks.  I bought a Grayskull of Ebay and now need to try and port the user mode driver to PPC.

Operating Systems and Porting / powerpc equivalent to x86 intrinsics?

« on: January 29, 2025, 11:07:59 pm »

Does anyone know of PPC equivalent asm or builtins for these gcc intel intrinsics?

Code: [Select]

_mm_sfence();
_mm_lfence();  __builtin_ia32_lfence (void);
_mm_mfence();

Oh, so (after reading the datasheet) the FLASH chip hardware WP isn't enabled by default. It would need to be configured by the BMC or external programmer.

I don't see how (or why) a Fedora install would change the pnor. There is a write protect switch on the motherboard that will prevent the BMC from writing to the FLASH chips.

The scp command needs the -o option.
Someone recently on this forum had that problem, it has something to do with new default settings in scp.

I couldn't get the web interface update to work either. It would always show an error when 'activating', even though the file is uploaded to /tmp.
I had to use the other method with the pflash program.

The FSI is the communication bus between the CPU and BMC.
Maybe re-flashing the BMC firmware will fix it?
