| | | | | | | | | | This reverts commit 5555545494c876adedf4f0038db49c1d85527e78. The target supports both NEON and VFPv4, but for this to work properly, a few more changes are needed: - enable NEON support in the kernel config - add the fpu feature flag to the makefile Signed-off-by: Felix Fietkau <nbd@nbd.name>

Just use sysupgrade -n -F sysupgrade.bin Syuspgrade needs to be forced since OpenWRT uses DT detection in recent releases. If you get error that FIT configuration is not found during boot it is due to older U-boot used on your board. That is because 8devices used custom FIT configuration partition name as they internally had v1 and v2 boards. Only v2 boards are sold so now they are shipping boards with never U-boot using generic config@1 FIT partition name. Also for old uboot it is possible to force loading config@1 by changing uboot environment: setenv boot5 'bootm 0x84000000#config@1’ saveenv Signed-off-by: Robert Marko <robimarko@gmail.com>
* kernel: mtd: bcm47xxpart: improve handling TRX partition sizeRafał Miłecki2018-04-125-2/+197
| | | | | | | | | | | | | | This is important fix for flash parsing in some corner cases. In case of TRX subpartition with rootfs being aligned to the flash block size it was incorrectly registered twice. Detecting & registering it as a standalone partition was resulting in an incorrect "firmware" partition size and possibly broken sysupgrade. It wasn't noticed before because "rootfs" alignment depends on a kernel size. It can happen though - depending on the configuration and the kernel size.

| | | | | | | | | | | | | | | | | | | | | | | | The Zorlik ZL5900V2 is an unbranded clone of HAME MPR-A1/2. It is marketed as "3G Wi-Fi Router". Only the PCB has the model name "ZL5900V2" printed on it. Specifications: - Ralink RT5350F (360 MHz) - 32 MB RAM - 8 MB Flash - 802.11bgn 1T1R - 1x 10/100 Mbps Ethernet - 1x USB 2.0 (Type-A) - 5200 mAh battery The ramdisk image (not the squashfs sysupgrade image) can be flashed through the web interface (named "GoAhead") of the factory firmware. However, as the factory firmware does not cleanly unmount the rootfs before flashing, the device may hang instead of rebooting after successful write. Power cycling the device gets you in OpenWrt where the squashfs image may be flashed through normal sysupgrade procedure. Signed-off-by: Vianney le Clément de Saint-Marcq <code@quartic.eu>

* ramips: add dwr-512 jboot firmware configurationGiuseppe Lippolis2018-04-085-15/+19
| | | | | | | | | | | | | | | | | | | | | The previous fw version require the replacement of the stock bootloader with u-boot. This prevent an easy stock restore of the original fw. Now a proper fw util has been developed to manage the stock jboot bootloader. Therefore make sense have a fw image for the stock bootloader. The old fw configuration (u-boot) is not compatible with the new one and will not be supported anymore. So at the end 2 image can be generated: 1) factory image with jboot bootloader openwrt-ramips-rt305x-dwr-512-b-squashfs-factory.bin 2) sysupgrade image with jboot bootloader openwrt-ramips-rt305x-dwr-512-b-squashfs-sysupgrade.bin Signed-off-by: Giuseppe Lippolis <giu.lippolis@gmail.com>

This device has a recovery system that assign the ip addr of env variable "serverip" via dhcp to a pc, and the "ipaddr" value to itself. The recovery it's triggered by a not bootable firmware, or pressing the reset button during the bootloader startup (first 30 seconds). The recovery uses a http page to restore the firmware, and it's checking the firmware image header, so use the "factory" image to restore or the original firmware. You can access vendor firmware over serial using: - login: root - password: linuxrocks Image was tested only in EU version of the device, but should work also with the same device version sold in other countries.
