TFTP 1.68 intelligent flash brush all-around version released, TTL line in the CFE mode to solve BCM5357 such as fixun FIR302B and other product brick change problems

Since its launch, TFTP has been favored by a large number of flash brush friends. Many people have been adding my Q: How to flash the machine?

I would like to tell you that, due to the wide variety of models, it is recommended that you have a problem with Baidu. If you are free, I can answer as much as possible.

Why is TFTP smart flash machine upgraded? There are two main reasons:

1. I recently helped the customer build a smart wifiDog firmware under FIR302B, OEM, simple setup, and smart Upload of device information to CEN certification.

The firmware cannot be started because it may cause a firmware problem during the firmware preparation process. Therefore, there is no way to update the firmware. (Fixun FIR302B cannot be directly flushed using the original TFTP, which is blocked by them)

Therefore, you can only use the CFE to upload firmware, that is, to save bricks.

2. I had a lot of friends talking to me about this problem last time, so I decided to fix it by the way.

Software: 1

Next I will explain to you with Feixun FIR302B, saving bricks:

This FIR302B is really abnormal, like other BCM5357 is not so troublesome, but this device is cheap. It only costs 39 RMB for one device, which is very cheap.

1. Will the TTL line be connected? (This model needs to be welded on its own, and the holes are reserved.) the parameters are 115200,8, N, 1.

2. Press CTRL + C to power on and enter the CFE mode.

3. Open the TFTP software

4. Select the firmware.

5. Click server mode to start the server flash mode. If the IP address of the local machine is not the IP address of your wired Nic, enter the IP address again and generate it. At this time, it will be automatically copied to the clipboard.

6. Enter CFE, right-click, paste, and press enter.
