===Firmware verification=== | |||
---- | |||
When you upload a firmware image, the device will have to verify the validity of that image. If the verification was a success, you will redirected to window with a message such as this: | |||
[[File:{{{Trb14x_webui_system_flash_firmware_verification_succeeded_v1.png}}}]] | |||
This means that the uploaded firmware image is compatible with your device. The indication also displays the file's MD5 and SHA256 checksums. A <b>checksum</b> is a sequence of hexadecimal symbols generated after running an algorithm called a cryptographic hash function on a file. Calculating a checksum and comparing it with the one provided by the file source can be used as a file authenticity check method. A list of {{#ifeq:{{{name}}} | TRB142 | {{{series}}} | {{{name}}}}} firmware checksums can be seen <b>[[{{#ifeq:{{{name}}} | TRB142 | {{{series}}} | {{{name}}}}} Firmware checksum list|here]]</b>. | |||
If everything is in order, you can click the <b>Proceed</b> button to initiate the upgrade or click <b>Cancel</b> to abort. | |||
On the other hand, if the uploaded a firmware file that is incompatible with your device, you will see an indication such as this: | |||
