humanus Posted yesterday at 07:18 PM Posted yesterday at 07:18 PM @alexc @qq20739111 I would be very surprised if the UART log showed anything other than mine. You can find it attached above. 0 Quote
alexc Posted yesterday at 07:53 PM Posted yesterday at 07:53 PM @humanus Thanks, just noticed the log. Interestingly looks like it's the mmc part. A few things I can think of: 1. emmc is only presented on A7A/S, so if you are using emmc or your board has an emmc, it might be a problem. You can try to disable sdc2 on device tree and see if it works. 1. sd card part is the same on A7A/S/Z, but I don't think my card is a UHS-II card. Looking at the log, it might be doing something with UHS-II, so it might be worth trying a different SD card to see if it behaves differently. If it does turn out to be related to UHS-II handling, I can look into a proper fix later. on. 0 Quote
humanus Posted yesterday at 08:12 PM Posted yesterday at 08:12 PM (edited) I have no eMMC and the card isn't UHS-II (I use WD Purple cards, they are UHS-I). I don't think I have any UHS-II cards at the moment... Could try a different one though. Edited yesterday at 08:13 PM by humanus clarify 0 Quote
alexc Posted yesterday at 10:23 PM Posted yesterday at 10:23 PM (edited) @humanus I took a second look at the log, I think it's probably due to the enabled eMMC. EDIT: I added the emmc part to my A7Z dts, it also crashes... So that's definitely the root cause. I disable it for A7S in my repo for now, you can compile it yourself with a Linux 6.18 kernel or wait for Nick. By the way A733 eMMC seems to use the same eMMC driver as A523, so probably mainline already supports it. Edited yesterday at 10:31 PM by alexc 1 Quote

The a7a board has m.2 pcie where the PentaHAT can be attached (I tested it with a custom sunxi kernel). Also want to ask about SATA support, specifically for PentaHat. I saw a thread on official forum https://forum.radxa.com/t/radxa-cubie-a7a-sata-support/29154 looks like electrically there is no issues. But are there necessary drivers in armbian?

qq20739111 Posted 3 hours ago Posted 3 hours ago @Nick A Hi Nick, I'm using your image (Radxa-cubie-a7z-v0.6.4_trixie_vendor_6.6.98_xfce_desktop.img) on my Radxa Cubie A7Z, which I've DIY-modified to have 6GB of RAM. Micron D9XKK (MT53E1536M32D4DT-046 AAT:A) 6GB LPDDR4 chip. Unfortunately, it fails to boot. Here is the UART output below. Do you know how to fix this? Does the system need specific configuration to recognize the 6GB RAM? ...... [212]HELLO! BOOT0 is starting!

humanus Posted 1 hour ago Posted 1 hour ago (edited) @alexc With the latest changes from you, incorporated by Nick, the 6.18 kernel boots. But there's a problem with PCI-Express. I can't get anything to work. I tried a GPU and a USB 3.0 hub, connected via a powered flex-to-pcie-1x adapter. Both are detected and get power but don't work. When I do lspci, the hub appears (the GPU doesn't) and when I try `lspci -t`, I get a segmentation fault. So something is wrong. Here is the log: https://paste.armbian.eu/akilodanus.yaml Edited 1 hour ago by humanus Clarify 0 Quote
alexc Posted 1 hour ago Posted 1 hour ago (edited) @humanus That's something we might need to work on next. I only have a M.2 board but my Raspberry Pi is using it right now. Let me see if I can use it to test later. So PCIE definitely works on 5.15/6.6, right? Your log doesn't really say where it crashes. For the GPU, what's the GPU? I don't think we built the kernel with any PCIE GPU drivers enabled, so that might be a potential problem. @Wintermute The same thing goes to the SATA. It's possible your PCIE to SATA controller is not supported/enabled in the kernel config (This applies to any kernel version). Edited 1 hour ago by alexc 0 Quote
