| kristianpaul | wpwrak: from the current understanding of softusb core, do you think it is more intented for ie, 'migrate' linux drivers for some usb devices than actually implementing the whole usb stack? | 04:03 |
|---|---|---|
| kristianpaul | i ask this in the ignorance of the usb internals on Linux as well, so i relly on your comments | 04:03 |
| kristianpaul | relay* | 04:04 |
| wolfspraul | rely | 04:04 |
| kristianpaul | he | 04:05 |
| kristianpaul | Thanks ! | 04:05 |
| wpwrak | kristianpaul: at the moment, it's all about implementing the stack on the navre. the FPGA core could be used for a more general architecture, though | 04:54 |
| wpwrak | (the FPGA core is very simple and thus quite generic. it's the navre who connects the dots) | 04:55 |
| qi-bot | The firmware build was successful, see images here: http://fidelio.qi-hardware.com/~xiangfu/build-milkymist/milkymist-firmware-20120404-1312/ | 12:53 |
| qi-bot | The firmware (using branch) build was successful, checkout the VERSIONS for detail, see images here: http://fidelio.qi-hardware.com/~xiangfu/build-milkymist/milkymist-firmware-20120404-1453/ | 14:33 |
| mwalle | lekernel: youre there? | 20:50 |
| lekernel | mwalle: yes | 21:34 |
| mwalle | lekernel: the navre io bus is 6 bit wide isnt it? | 21:52 |
| mwalle | for some reason rio8(0x11) doesn't work, mhh | 21:54 |
| lekernel | well, it should. what happens? | 22:12 |
| mwalle | lekernel: reads some garbage. i extended the switch statement in softusb_sie.v, with another (lower) address, it works | 22:15 |
| mwalle | lekernel: never mind, i'll try to simulate it tomorrow | 22:15 |
| lekernel | aha. maybe you've found a bug. | 22:20 |
| jpbonn | can anyone tell me why I get different values when reading 0x60001074 and 0xe0001074? Doesn't 0x60001074 shadow 0xe0001074? This is using gdb on qemu. | 22:35 |
| lekernel | 0xe... is non cacheable (wrt L1) while 0x6... is - but afaik it shouldn't make a difference when using qemu | 22:46 |
| lekernel | though I'm not sure if qemu implement CSRs correctly at 0x6..., since they should always use non cacheable access :) | 22:46 |
