NEEK example with ocm mmc_spi and mmu

This sounds GREAT !

I'll try to recreate the Binary Linux Distribution - with MMU - based on this ASAP (which will be not that soon right now :( ).

Is there anything that might prevent booting this from the SD-Card with the Altera Application Loader (no u-boot) ?

I suppose ALTUART without FIFO will not work decently. What prevents using the fifoed UART ?

I suppose still no change signal for the SD-Card (AFAIU, this is a PCB design issue) ?

How is the remote update going to work (e.g. FTP a new FPGA design file and/or Kernel Image (with embedded initramfs)

What is the difference between ethoc and oeth ? I used oeth with NEEK-nommu and the latest versions of "hardware" and driver seemed to weor perfectly.

Hi,

Thank you, Hippo. I just want a storage. I will enjoy it! And I will try to make 'swap', though this means to enter the nest of BUGs:D.

Michael,

1. I think it should work with application selector.

2. I want to know if there is anything slow down the handling of a 115200 baud uart.

3. no sdcard change signal, there is no wire to fpga on the pcb.

4. it is a interface to the remote update ip core. please read the data sheet and driver code to find out. I've tried it yet.

5. they work similar. ethoc is more up to date and is in the mainline kernel. open_eth might be removed in the future.

Kazu,

You are incredible! Superb.

I understand that the non-FIFO UART receive does not work decently (loose characters) with more than some 2400 Baud.

I suppose you did not try it yet ?

I'll talk to Frank Storm about this and will try to find out if there is a way to enhance this to a secure way of updating the FPGA design and the Software via FTP. This will involve at least two copies of both in the flash and use a mechanism that starts a working one of them (the "old should work anyway, the "new" might be the result of a corrupted update).

The Cyclone III does handle this for the FPGA design by hardware, regarding the software the bootloader needs to do this.

So I suppose this needs a different boot loader but the "Application Selector".

Is this just another driver for the same hardware design ?

Yes.
