I've flashed a different sample code on CYW920735Q60EVB-01, how can I go back to the original HCI firmware
Thanks for your reply
I am looking for the original firmware that came with the board during the time of purchase. The one that we could attach to bluez via hci
Unfortunately there is no way to retain that firmware. But you can do recovery procedure and configure the board to receive HCI commands. Please check https://community.cypress.com/t5/Resource-Library/Running-BlueZ-on-CY-Part/ta-p/246050
Thanks for your reply.
After following all the steps, as mentioned on the blog still HCI is not working out.
This hci1 BD address is 00:00:00:00:00:00. Which seems very unreliable.
Please help me to solve this issue.
Thanks a lot
Have you programmed the board sing an empty application first?
Have you tried resetting the board as mentioned in the blog? Is it not working?
Yes, I follow all the steps. and flash the hello sensor program. as well as press the reset button..But still, it's not working out.
Hi @Vaibhav330900 ,
As mentioned in the KBA above (recommended to download an empty Application), You should first program the device with an empty application, not the hello sensor project.
Your .c file should not contain any infromation, keep only source file name in makefile. No wiced_bt_cfg.c file required. Just the source .c and makefile should work. First recover the board using recovery procedure and then program your board with attached empty application.
Ideally, you should be able to setup communication using the procedure mentioned in the KBA.
1. Press and hold RECOVER button (SW1) |
2. Press and hold RESET button (SW2) for 1 second |
3. Release SW2 |
4. Release SW1 |
5. Program the board |
Your Make Target is incorrect. Please follow the standard format-
<app_name>-<board name> download
ex. empty-CYW920735Q60EVB_01 download
Make sure you dont have HCI COM port open anywhere else.
More details on how to program the board can be found in kit user guide.
Hi, Thanks a lot for your support. I have recovered the HCI of my cypress board.
Thanks a lot
