| _florent_ | cr1901_modern: from a system point on view, i don't see why you want to support multiblock and then use CSRs to fill your data | 00:01 |
|---|---|---|
| _florent_ | cr1901_modern: in this case, i'm probably sure using CSRs you won't be able to saturate single block writes | 00:01 |
| _florent_ | cr1901_modern: also the requirement is that you only send a write command when you know that you have at least 512 bytes in the buffer | 00:02 |
| cr1901_modern | _florent_: My main point is: how can a LiteX SoC keep the litesdcard core filled w/ data if LiteX SoCs don't have DMA? | 00:04 |
| cr1901_modern | Perhaps one could allocate a buffer larger than 512 bytes for wishbone storage that litesdcard core reads | 00:05 |
| cr1901_modern | But I've never used the stream/source/sink interfaces; I don't know how to make it "look like" a FIFO on the SD card side, and a contiguous block of memory on the CPU side | 00:06 |
| _florent_ | cr1901_modern: we have multiple dma modules, but it always depends what you want to do | 00:11 |
| cr1901_modern | _florent_: That's up to mithro, but seeing as he's not here >> | 00:12 |
| cr1901_modern | _florent_: I want a data buffer exposed in the CPU address space for reads and writes. On the SD card side, every time a read/write occurs >> | 00:13 |
| cr1901_modern | the SD card starts reading/write from index 0 from that chunk of address space, like a FIFO | 00:13 |
| _florent_ | cr1901_modern: then yes you can create a wishbone memory on the cpu side + some logic to read/write this memory on the sd card side | 00:14 |
| cr1901_modern | Is there a simple way to do this from LiteX, or do I have to create an FSM to- ohh, I see | 00:15 |
| cr1901_modern | Idk if that's what SoCs normally do, I'll spend some time reading an RPi manual or something tomorrow. | 00:15 |
| cr1901_modern | To get an example of "prior art". | 00:15 |
