I found some time to rip one out of the installation, solder a cable to the UART pins and boot with a serial console attached. I configured /boot/firmware/config.txt: ``` enable_uart=1 uart_2ndstage=1 ``` When I boot with 6.12.48+deb13-rpi it hangs here: ``` Raspberry Pi Bootcode Read File: config.txt, 532 Read File: start.elf, 2981056 (bytes) Read File: fixup.dat, 7303 (bytes) MESS:00:00:01.252151:0: brfs: File read: /mfs/sd/config.txt MESS:00:00:01.256416:0: brfs: File read: 532 bytes MESS:00:00:01.292170:0: HDMI0:EDID error reading EDID block 0 attempt 0 MESS:00:00:01.298336:0: HDMI0:EDID error reading EDID block 0 attempt 1 MESS:00:00:01.304672:0: HDMI0:EDID error reading EDID block 0 attempt 2 MESS:00:00:01.311009:0: HDMI0:EDID error reading EDID block 0 attempt 3 MESS:00:00:01.317346:0: HDMI0:EDID error reading EDID block 0 attempt 4 MESS:00:00:01.323683:0: HDMI0:EDID error reading EDID block 0 attempt 5 MESS:00:00:01.330019:0: HDMI0:EDID error reading EDID block 0 attempt 6 MESS:00:00:01.336356:0: HDMI0:EDID error reading EDID block 0 attempt 7 MESS:00:00:01.342693:0: HDMI0:EDID error reading EDID block 0 attempt 8 MESS:00:00:01.349030:0: HDMI0:EDID error reading EDID block 0 attempt 9 MESS:00:00:01.355125:0: HDMI0:EDID giving up on reading EDID block 0 MESS:00:00:01.361505:0: brfs: File read: /mfs/sd/config.txt MESS:00:00:01.365951:0: gpioman: gpioman_get_pin_num: pin LEDS_PWR_OK not defined MESS:00:00:01.558660:0: gpioman: gpioman_get_pin_num: pin LEDS_PWR_OK not defined MESS:00:00:01.564486:0: *** Restart logging MESS:00:00:01.568364:0: brfs: File read: 532 bytes MESS:00:00:01.573602:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 0 MESS:00:00:01.580979:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 1 MESS:00:00:01.587837:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 2 MESS:00:00:01.594695:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 3 MESS:00:00:01.601552:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 4 MESS:00:00:01.608410:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 5 MESS:00:00:01.615267:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 6 MESS:00:00:01.622126:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 7 MESS:00:00:01.628983:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 8 MESS:00:00:01.635841:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 9 MESS:00:00:01.642457:0: hdmi: HDMI0:EDID giving up on reading EDID block 0 MESS:00:00:01.648361:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 0 MESS:00:00:01.656152:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 1 MESS:00:00:01.663011:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 2 MESS:00:00:01.669869:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 3 MESS:00:00:01.676725:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 4 MESS:00:00:01.683584:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 5 MESS:00:00:01.690442:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 6 MESS:00:00:01.697299:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 7 MESS:00:00:01.704157:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 8 MESS:00:00:01.711015:0: hdmi: HDMI0:EDID error reading EDID block 0 attempt 9 MESS:00:00:01.717630:0: hdmi: HDMI0:EDID giving up on reading EDID block 0 MESS:00:00:01.723244:0: hdmi: HDMI:hdmi_get_state is deprecated, use hdmi_get_display_state instead MESS:00:00:01.731991:0: HDMI0: hdmi_pixel_encoding: 162000000 MESS:00:00:01.737705:0: vec: vec_middleware_power_on: vec_base: 0x7e806000 rev-id 0x00002708 @ vec: 0x7e806100 @ 0x00000420 enc: 0x7e806060 @ 0x00000220 cgmsae: 0x7e80605c @ 0x00000000 MESS:00:00:02.620274:0: brfs: File read: /mfs/sd/initrd.img-6.12.48+deb13-rpi MESS:00:00:02.625721:0: Loaded 'initrd.img-6.12.48+deb13-rpi' to 0x0 size 0xe0bfdc MESS:00:00:02.649671:0: initramfs loaded to 0x1b1e4000 (size 0xe0bfdc) MESS:00:00:02.664189:0: dtb_file 'bcm2835-rpi-zero-w.dtb' MESS:00:00:02.667900:0: brfs: File read: 14729180 bytes MESS:00:00:02.675736:0: brfs: File read: /mfs/sd/bcm2835-rpi-zero-w.dtb MESS:00:00:02.680655:0: Loaded 'bcm2835-rpi-zero-w.dtb' to 0x100 size 0x4c27 MESS:00:00:02.696926:0: brfs: File read: 19495 bytes MESS:00:00:02.747687:0: brfs: File read: /mfs/sd/config.txt MESS:00:00:02.756796:0: brfs: File read: 532 bytes MESS:00:00:02.760416:0: brfs: File read: /mfs/sd/cmdline.txt MESS:00:00:02.765284:0: Read command line from file 'cmdline.txt': MESS:00:00:02.771168:0: 'console=tty0 console=ttyS1,115200 root=/dev/mmcblk0p2 rw fsck.repair=yes net.ifnames=0 cma=64M rootwait' MESS:00:00:02.799201:0: gpioman: gpioman_get_pin_num: pin EMMC_ENABLE not defined MESS:00:00:02.856093:0: brfs: File read: 105 bytes MESS:00:00:03.137459:0: brfs: File read: /mfs/sd/vmlinuz-6.12.48+deb13-rpi MESS:00:00:03.142614:0: Loaded 'vmlinuz-6.12.48+deb13-rpi' to 0x8000 size 0x498c60 MESS:00:00:03.149917:0: Device tree loaded to 0x1b1dee00 (size 0x51ad) MESS:00:00:03.156884:0: uart: Set PL011 baud rate to 103448.300000 Hz MESS:00:00:03.163845:0: uart: Baud rate change done...
