10:57 <nickoe> _florent_: What could the reasons be that LiteDRAMDMAReader() will appear to buffer stuff in the fifo, but it does not seem like the data is anything but zeros?

11:11 <nickoe> I was expecting to see the data in the beginning of main_ram, where the demo.bin is dumped, and I also tried the data I put at 0x41000000 via boot.json

11:11 <nickoe> main_ram : Origin: 0x40000000, Size: 0x04000000, Mode: RW, Cached: True Linker: False

11:42 <thorns514> hi folks - I'm trying to track down some strange errors in my numato mimas a7 - what does it mean if the post-reset memory test in the LiteX bios console sometimes passes and sometimes fails?

11:43 <thorns514> (I've had a probably-unrelated problem of being unable to program this board over JTAG with a digilent cable, but only when on USB power)

11:48 <nickoe> maybe the memory is mis configure, maybe your power supply is wonky?

11:52 <thorns514> it seems to be about 50:50 even with the power supply disconnected and running off of USB power

11:58 <nickoe> does it work stable for other boards/people. I am not really familiar with the board

12:01 <thorns514> yeah I don't know, the example came from the manufacturer https://numato.com/kb/running-micropython-on-mimas-a7-using-litex-and-migen/ so I presume I wasn't supposed to have to go research sdram timings
