===== Manual U-boot TFTP flashing =====

**These instructions are for Jalapeno board**

  * You will need TFTP server running on your PC. On Linux install package 'tftpd-hpa', on Windows - [[http://tftpd32.jounin.net/|TFTPD32]].

  * Put sysupgrade image to your TFTP folder.

  * Reboot or power up Jalapeno with serial console running and connected to PC.

  * Set server ip (in our case it is 192.168.2.254) on your network interface to which Jalapeno is connected.

  * Copy u-boot firmware to tftp server directory and rename it to fwupdate.bin:

  sudo cp lede-ipq806x-Jalapeno-squashfs-nand-factory.ubi /var/lib/tftpboot/fwupdate.bin

  * Run u-boot upgrade command:

  (IPQ40xx) # run do_recovery
