Hi I’m doing a bringup on a computer based on Phytecs phyCORE-AM335x. Unfortunately I need support for a newer kernel than the one that Phytec supports (3.12). Mainline kernel 4.4 is supposed to work ”out of the box” on this module, but I have a problem booting the machine: I use Barebox as bootloader and it works up until the point where the kernel is loaded. Then it halts with no output whatsoever. I have the 4.4 kernel configured as close as possible to the known working config of 3.12, and if I exchange the 4.4 image with 3.12 it works as expected. I’m running out of ideas and since there is no console output at all I don’t know how to debug this any further… Any hints? Here is the bootloader output: ===== start ===== barebox 2015.09.0 #1 Tue Feb 2 15:01:29 CET 2016 Board: Phytec phyCORE AM335x omap-hsmmc 48060000.mmc: registered as 48060000.mmc booting from MMC mmc0: detected SD card version 1.10 mmc0: registered mmc0 barebox 2015.09.0 #6 Wed Feb 17 12:33:02 CET 2016 Board: Phytec phyCORE AM335x cpsw 4a100000.ethernet: detected phy mask 0x5 mdio_bus: miibus0: probed eth0: got preset MAC address: ec:24:b8:c0:bd:89 am335x-phy-driver 47401b00.usb-phy: am_usbphy 8ff20a14 enabled musb-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn) musb-hdrc: MHDRC RTL version 2.0 musb-hdrc: setup fifo_mode 4 musb-hdrc: 28/31 max ep, 16384/16384 memory m25p80 m25p80@00: s25sl064p (8192 Kbytes) i2c-omap 44e0b000.i2c: bus 0 rev0.11 at 400 kHz omap-hsmmc 48060000.mmc: registered as 48060000.mmc mmc0: detected SD card version 1.10 mmc0: registered mmc0 OMAP Watchdog Timer Rev 0x01 nand: ONFI flash detected nand: NAND device: Manufacturer ID: 0x2c, Chip ID: 0xdc (Micron MT29F4G08ABADAH4), 512MiB, page size: 2048, OOB size: 64 netconsole: registered as netconsole-1 malloc space: 0x8ff00000 -> 0x9fdfffff (size 255 MiB) environment load /boot/barebox.env: No such file or directory Maybe you have to create the partition. running /env/bin/init...
