deviation-bootloader

Replacement Bootloader for Deviation supported transmitters.

NOTE: Unless you are a developer, you should NOT install this bootloader yet!

Installing this bootloader requires a custom Deviation build to enable, which is not provided by current nightlies

This bootloader currently provides the following functionality for supported transmitters:

• LCD display when in bootloader mode
• support for SPI read/write
• non-encrypted DFU files

Currently supported transmitters

• Jumper T8SG-V1
• Jumper T8SG-V2
• Walkera Devo-7e
• Walkera Devo-7e w/ 256k mod

###Compiling It is important to properly build for the intended tarnsmitter

• T8SGV1: make TXVER=T8SGV1
• T8SGV2: make TXVER=T8SGV2
• T8SGV2+: make TXVER=T8SGV2+
• Devo7e: make TXVER=DEVO7E
• Devo7e w/256k: make TXVER=DEVO7E-256

Installing the bootloader

If you currently have the default Walkera/Jumper Bootloader installed:

• Install installer-enc-<target>.dfu using Deviation-Uploader

If you currently have an older version of Deviation Bootloader (>= 0.10.0):

• Install installer-<target>.dfu using Deviation-Uploader

Developer testing

If you would like to preserve your existing bootloader, we currently support a two-stage bootload option. Set the 'TWO_STAGE' variable=1 in the makefile. Only the unified t8sg build will work with the two-stage bootloader! You cannot load any other builds when using this mode of operation

Installing a deviation build when using deviation-bootloader

Encryption must be removed prior to installing a new firmware when using the Deviation Bootloader. This can be done by re-runniing utils/dfu.py with -c 0 and with 'Unified' in the description string. For example, to install the stock t8sg-v2+ image after installing deviation-bootloader:

make t8sg_v2_plus
./../utils/dfu.py --name "t8sg_v2_plus-v5.0.0-xxxxxxx Unified Firmware" -c 0 -b 0x08003000:t8sg_v2_plus.bin t8sg_v2_plus.dfu
