When firmware update goes wrong!!

Thu Aug 10, 2017 2:59 am

Hi All

I hope some one here can be of assistance, new to the world of Vocore2;

I have completely halted my system, here is the output from TTL via windows using putty;

<snip>
*** Warnirigger enabled
GPIO 46 used to trigger webpage
Hold button for between 3 seconds and 6 seconds
then release to trigger webpage to load image
Hold button for between 6 seconds and 9 seconds
then release to trigger loading image from USBSTORAGE
GPIO 46 is low

You chose 3
0

3: System Boot system code via Flash.
## Booting image at bc050000 ...
Image Name: MIPS OpenWrt Linux-3.10.49
Image Type: MIPS Linux Kernel Image (lzma compressed)
Data Size: 1006224 Bytes = 982.6 kB
Load Address: 80000000
Entry Point: 80000000
Verifying Checksum ... OK
Uncompressing Kernel Image ... OK
No initrd
## Transferring control to Linux (at address 80000000) ...
## Giving linux memsize in MB, 128

<snip end>

The system is now frozen, any help would be appreciated. Point me in the right direction, many thanks in advance.

default we are using UART2 as debug port, looks like your firmware is not using VOCORE2.dts, so debug console is changed after you update the firmware.
Try to fix your firmware and make it using UART2 as debug console port, then use kermit and uboot upload the firmware, it will recover.

PS: VoCore2 firmware default enable wifi, but if you compile from openwrt/lede, wifi is default off. you can connect to your VoCore2 by ethernet and setting /etc/config/wireless, remove the disable setting.

Thanks for the reply Vonger,



but no joy using kermit, the port /dev/ttyACM0 connects but no response from Vocore2. I also tried connecting to the device via ethernet, but also dead no response(tried both 192.168.1.1 & 192.168.61.1after some reading).

Thanks for your prompt suggestions.
