| Would a Pinebook Pro be good for a Linux newbie? |

I missed out on the Pinetab before (which might've been the preferred device). I'm aware it's ARM, and that it's possible to load Linux on Windows laptops via USB etc. I've seen the "What Are The Current Strengths & Weaknesses of Pinebook Pros?" thread. I understand there are other alternatives if we're just talking specs.
But it would be nice to have a device made for Linux, and something that just does Linux when you switch it on (...I assume). I'm interested in ease of use. There doesn't seem to be anything in the way of "entry-level" Linux. I hope the PbP is the answer to this.

| Does latest Tow-Boot install/work correctly for everyone? |

After a few years of rocking a BSP img on my emmc (for that sweet S3) and not booting into it, I'd like to switch fully to a modern install of Fedora since I've been booting a pre EFI Fedora img from SD as my unofficial main boot.
Since Tow-Boot is needed for a modern Fedora install, I went and grabbed the latest version (2022.07-006) from Github. After writing spi.installer.img to several different and known working SDs, as well as using dd, nandwrite, and flashcp to write it directly to /dev/mtd0 (all indicated successful writes in terminal) I cannot get my PBP to boot into the installer menu, or show anything tow boot related at boot up when writing directly to the SPI. (At most, I get a solid-lit green power LED and a black screen when booting the SPI installer SD.)
I've also tried going back a few versions, including 2021.10-005 and 2021.10-03 (which I recall successfully booting and installing a year+ ago) and I get the same results from them too.
So I'm curious now if anyone else has had this or a similar issue when trying to install tow-boot through SD installer or writing directly to mtd0 from within a booted OS. I'd raise it as an issue on the Github, but I want to be sure I haven't overlooked any potential solutions and I know @samueldr has indicated he isn't able to be as active in maintaining/troubleshooting as before.
EDIT: it was pointed out, I should add the commands I've run to write the installer to SD, and the .bin to SPI. Please note, the SD card is read as sda by the system.
dd (as per the tow-boot pbp page:
Code: sudo dd if=spi.installer.img of=/dev/sda bs=1M oflag=direct,sync status=progress
nandwrite:
Code: sudo nandwrite -p /dev/mtd0 Tow-Boot.spi.bin
flashcp:
Code: sudo flashcp Tow-Boot.spi.bin /dev/mtd0
I ran
Code: sudo flash_erase /dev/mtd0 0 0
between each nandwrite or flashcp.

Bonjour à tous et à toutes,
en France et à Toulouse, l'association Toulibre organise un événement de deux jours, le Capitole du Libre, autour du logiciel libre et de la culture libre.
Il aura lieu cette année le 18 et 19 novembre et comme à son habitude, dans les locaux de l'école d'ingénieurs INP-ENSEEIHT.
Conférences, ateliers, démonstrations et village associatif sont présents tout au long du week-end.
La présence de la communauté Pine64 dans le village associatif serait intéressante pour présenter les projets en cours et à venir.
Si une conférence en français ou en anglais est possible, ce serait formidable.
Les premiers échanges peuvent s'effectuer via le forum.
A bientôt,
|

| Thoughts on repairs for a Quartz64-B |

Hello,
I purchased new a Quartz64-b, and eventually found out that the Ethernet is faulty. ...after the 30 days warranty.
(I'm not a complete newb with SBC, but I got it, then ordered a Uart dongle later on, and that took its time to arrive and 30 days later...)
The errors for reference:
[ 163.788898] rk_gmac-dwmac fe010000.ethernet end0: PHY [stmmac-0:01] driver [RTL8211F Gigabit Ethernet] (irq=POLL)
[ 164.790182] rk_gmac-dwmac fe010000.ethernet: Failed to reset the dma
[ 164.790836] rk_gmac-dwmac fe010000.ethernet end0: stmmac_hw_setup: DMA engine initialization failed
[ 164.791683] rk_gmac-dwmac fe010000.ethernet end0: __stmmac_open: Hw setup failed
[ 165.410902] rk_gmac-dwmac fe010000.ethernet end0: Register MEM_TYPE_PAGE_POOL RxQ-0
[ 165.504999] rk_gmac-dwmac fe010000.ethernet end0: PHY [stmmac-0:01] driver [RTL8211F Gigabit Ethernet] (irq=POLL)
[ 166.513886] rk_gmac-dwmac fe010000.ethernet: Failed to reset the dma
So, a cautionary tale maybe? What to do?
Either: 1) wait - it may be a firmware issue. It hasn't been confirmed.
2) repair it somehow? That seems very difficult.
3) work around it. Wifi is working and a USB Eth --provided its NOT in the USB3 socket.
So, be careful. The quality control may not be there entirely. I don't know.
When you get it in the mail - test it ASAP, but then again you may not know all the faults with the device before the 30days is up .
Would I buy one again? ....probably not.

| [Article] Star64 JH7110 + NuttX RTOS: RISC-V PLIC Interrupts and Serial I/O |

Apache NuttX RTOS on Star64 JH7110 RISC-V SBC is almost ready! But we're stuck with 16550 UART Controller firing too many Spurious Interrupts.
In this article, we explain…
(1) Why there’s No Console Output from NuttX Apps
(2) How Serial I/O works in NuttX QEMU
(3) How UART I/O differs for Star64 vs QEMU
(4) What’s the RISC-V Platform-Level Interrupt Controller (PLIC)
(5) Why we delegate RISC-V Machine-Mode Interrupts to Supervisor-Mode
(6) How NuttX Star64 handles UART Interrupts
(7) Which leads to a new problem: 16550 UART Controller fires too many Spurious Interrupts!
