| psychotrope | stekern_: any guide on how to set that up? how much storage do you have now? can you boot linux from MMC? | 00:45 |
|---|---|---|
| psychotrope | that sounds awesome though :D | 00:45 |
| stekern_ | psychotrope: I just soldered SD->microSD onto a breakoutboard that I connected to the de0-nano | 00:52 |
| -!- stekern_ is now known as stekern | 00:52 | |
| psychotrope | stekern: yeah, but what about the logic to get that talking to the CPU? | 00:53 |
| psychotrope | the physical part of things is straight foward enough | 00:53 |
| stekern | theoretically you should be able to boot linux from scratch from it, but there's no sdcard support in the bootrom | 00:53 |
| stekern | you communicate with it with the SPI controller | 00:54 |
| psychotrope | but I'm not familiar with the IO options on the DE0 nano other than the wishbone bus and the UART port | 00:54 |
| psychotrope | okay, I think I can make this work... | 00:55 |
| psychotrope | is the storage hot-swap by chance? | 00:55 |
| psychotrope | I'll have an external device write the linux kernel directly into RAM, and then use the SPI MMC from there | 00:55 |
| psychotrope | I need 2 storage devices | 00:56 |
| stekern | yes, I don't see why it wouldn't bee | 00:56 |
| stekern | be | 00:56 |
| psychotrope | awesome | 00:56 |
| psychotrope | I'll pass on messing with bootrom, much easies to much use a microcontroller to program the RAM | 00:56 |
| psychotrope | and I assume there would be no issue accessing the SPI storage from linux once it was loaded to RAM? | 00:57 |
| psychotrope | what I'm going for is microcontroller == loads linux ==> DEO-nano RAM == accesses SPI and makes it usable in linux ==> MMC | 01:45 |
| ssvb | is everyone okay with this "OpenRISC: Remove" patch for U-Boot? https://patchwork.ozlabs.org/patch/738757/ | 07:57 |
| bandvig | ssvb: It is very bad idea for me. I use U-Boot all the times on Atlys board. | 08:04 |
| shorne | ssvb: can you cc the openrisc list if possible? openrisc@lists.librecores.org | 11:07 |
| shorne | stekern: maybe doesn't update it anymore but I guess there are users | 11:08 |
| shorne | even psychotrope today is asking about booting openrisc on an sd card, would probably need u-boot for that | 11:08 |
