 Pratham Patel | By flash, do you mean the QSPI flash on board? | 17:29:28 |
 Alex | Yes, it's the setting called "flash" on the printout on the board itself. | 17:29:49 |
| Pratham Patel | Okay I'll give it another go | 17:30:07 |
| Alex | Honestly though, I'm amazed that you managed to boot misuzu's image at all after screwing with the partitions. | 17:30:55 |
| Pratham Patel | I inserted an old SD card (which didn't manipulate the partitions) and now the console complains this:
switch to partitions #0, OK

| Pratham Patel | I know why I did the partition makeover lol | 17:31:42 |
| Alex | It looks to me like that's in SDIO boot mode? | 17:31:56 |
| Pratham Patel | Nope, I'm booting from flash | 17:32:06 |
| Alex | Switches on 0, 0?
Weird. | 17:32:31 |
| Pratham Patel | U-Boot SPL 2021.10 (May 31 2023 - 16:54:00 +0800)

Weird. Yep, 00 | 17:32:38 |
| Pratham Patel | I don't know the Nix expression langauge, like, at all otherwise I would've sent in the PR to boot from SD. I hate the booting from SD card approach but since uboot is on SD card, we know what uboot the user is using. | 17:35:46 |
| Alex | Latest from vendor should work.
Are you able to boot misuzu's image in SPI mode? | 17:36:30 |
| Pratham Patel | I'll check the latest vendor firmware | 17:36:51 |
| Pratham Patel | In reply to @alex:tunstall.xyz
Latest from vendor should work.
Are you able to boot misuzu's image in SPI mode? not in SPI mode (with the firmware flashed using nix run github:misuzu/nixos-vf2#flash-visionfive2-vendor /dev/ttyUSB0) | 17:37:07 |
| Pratham Patel | I will recheck using the latest stock firmware | 17:38:41 |
| Alex | You might need to flash the latest firmware in the vendor's Debian system.
The "upstream" kernel's DTB has a broken SPI partition table that is too small to flash all of the u-boot file. | 17:38:44 |
| Pratham Patel | I don't understand what you mean by the last sentence... | 17:39:18 |
| Alex | $ cat /proc/mtd
dev: size erasesize name
mtd0: 00020000 00001000 "spl"
mtd1: 00300000 00001000 "uboot"
mtd2: 00100000 00001000 "data"
mtd0 has a size of 128KiB, but the latest versions of u-boot exceed that. | 17:40:05 |
| Alex | Sorry, I probably should've mentioned this sooner. | 17:40:40 |
| Pratham Patel | That's why I prefer booting from SD Card for development purposes :) | 17:41:09 |
| Pratham Patel | I belive they have switched their priorities to porting EDK2 | 17:41:27 |
| Alex | This isn't a problem on the vendor's Debian, because the devel branch of the kernel has a different partition table. | 17:41:27 |
| Alex | Can you describe what needs to be done to boot from SD?
I might be able to make the change. | 17:41:51 |
| Pratham Patel | Just a sec | 17:42:10 |
| Pratham Patel | I use this partition layout for the first two partitions
https://github.com/thefossguy/archlinux-visionfive2/blob/master/create-image.sh#L85 | 17:42:46 |
| Pratham Patel | Then, you dd u-boot-spl.bin.normal.out to part1 and visionfive2_fw_payload.img to part2 | 17:44:13 |
| Alex | So 4 partitions:
- SPL (u-boot metadata)
- u-boot (flat binary)
- boot (FAT)
- root
Makes sense. | 17:44:29 |
| Pratham Patel | So instead of reading firmware from flash, the firmware is entirely read from the SD card ;) | 17:44:31 |

Makes sense. Exactly! | 17:44:44 |
