| pdp7 | gregdavill: is there a way for me to stop the crab from booting vexriscv and keep at the litex bios prompt? | 01:09 |
|---|---|---|
| pdp7 | when I open serial port /dev/ttyUSB0, it immediately boots | 01:10 |
| gregdavill | Hmm, I suppose it's checking the FLASH, and seeing a valid image there... | 01:11 |

| sajattack[m] | spisdcardboot was added in the last week or so | 01:16 |
| sajattack[m] | probably just hasn't made it into whatever codebase you're working from yet | 01:16 |
| sajattack[m] | or hasn't been enabled | 01:16 |
| sajattack[m] | have a look at make.py to enable it | 01:17 |
| pdp7 | gregdavill: do you have that in your build? | 01:19 |
| sajattack[m] | looks like it's enabled on master | 01:19 |
| pdp7 | I got the bitstream I'm running on the crab from greg | 01:19 |

| pdp7 | sajattack[m]: thanks | 01:20 |
| *** tcal has joined #litex | 01:20 | |
| gregdavill | for testing the spisdcardboot you'll need to load the bitstream _florent_ has made. | 01:21 |
| pdp7 | oh, so load it via dfu? | 01:21 |
| pdp7 | not just put it on sdcard | 01:21 |
| gregdavill | So load this via DFU: https://github.com/litex-hub/linux-on-litex-vexriscv/files/4382870/orangecrab_usb_cdc_spisdcard.zip | 01:22 |
| gregdavill | Then put the Linux files on the SD card. | 01:22 |
| gregdavill | This is specifically to load Linux files from the SD card instead of FLASH. | 01:22 |
| pdp7 | gregdavill: thanks, that was my misunderstanding | 01:24 |
| gregdavill | I have a separate bootloader that can load a bitstream off the SD card. But that was developed for the ButterStick needs a bit of porting work to get working on the Crab. | 01:24 |
| pdp7 | so something like: | 01:26 |
| pdp7 | dfu-util -d 1209:5bf0 -D top.bit ? | 01:26 |
| *** tcal has quit IRC | 01:27 | |
| gregdavill | Yep, that should do it. | 01:27 |

| gregdavill | So your card probably does need to be formatted as FAT16. Which might also mean trying to find a low capacity card? <2gb | 02:01 |

| dkozel | _florent_: JTAG arrived, installed, mostly working, bitstream programmed. | 13:06 |
| dkozel | Trying to build the kernel driver now, missing some dependency so working on that now | 13:06 |

| dkozel | netv2/software/kernel/main.c:604:54: error: unknown type name ‘poll_table’ | 13:41 |
| dkozel | 604 | static unsigned int litepcie_poll(struct file *file, poll_table *wait) | 13:41 |
| dkozel | Hmm | 13:41 |
| dkozel | Missing <linux/poll.h>? | 13:44 |
| dkozel | also <linux/cdev.h>? | 13:46 |
| dkozel | Usually that makes me guess my setup is broken somehow. With those the kernel module builds | 13:46 |
| dkozel | I have the kernel module loaded but no /dev/litepcie device is present. Have to switch to some other stuff for a few hours, but will try to figure out the module tonight | 14:53 |
