11:15 <jeandet_> Hello, finally I was able to get something working with enough performances to start measurements. I gave up for now with SD mode on ULX3S, I'll investigate later. I had to write my own SPI in order to work at sys_freq without any freq div and implement 32 bits transactions, that allowed me to reach 4MB/s write speed @60MHz. The current setup is quite basic, ADC->DMA->SDRAM->CPU->SDCARD. I'm really happy with LiteX so far :).
