| salmansheikh | on fuse_soc de0_nano, I am trying to print a loop of 10 float multiplications by a constant and program only runs through 2 + iterations...why? | 13:38 |
|---|---|---|
| homeless_ | hi everyone? | 13:39 |
| homeless_ | I have a question: Should I consider the calibration time of DDR2 (~40us) in bootrom code? I mean should I insert a delay code if I read from SPI flash and write to DDR2 ram? | 13:41 |
| homeless_ | I am using atlys board | 13:42 |
| stekern | the memory write will stall until the calibration has been performed, so no you don't need to | 13:43 |
| olofk | andrzejr: There should be an rmii2mii adapter somewhere... can't remember where right now | 13:43 |
| salmansheikh | could it be the size of the boot rom that is the problem? | 13:44 |
| homeless_ | stekern: so you are saying program counter will not increase until it gets calibrated? | 13:45 |
| stekern | homeless_: basically yes, the databus access will stall, which will stall the processor (at some point) | 13:45 |
| homeless_ | Ok. Thanks stekern. | 13:46 |
| homeless_ | Then, DDR' calibration cannot be the source of my problem. I should look somewhere else. | 13:48 |
| salmansheikh | no answers..eh..I will search myself... | 13:50 |
