How to download test.mfg_test to CYW43907 RAM and run without SFLASH.
By this we can set the OTP data independently .
No need download mfg_test to SFLASH to set OTP and then download the product's apllication.
Set SECURE_BIT in OTP then replance the application FW in SFLASH, it's high risk.
Regards!

Hi @Max_Li ,
OTP programming require mfg_test firmware. If you are planning to enable secure bit, refer section "6.5 Enable Secure Bit" in the document for which link attached below.
Thanks,

Hi Rakesh,
Thanks for your reply!
Like the AN mentioned in 6.5:
"Download the target application. This must be done before step 4 (power cycle), otherwise the JTAG port will be disabled and the application download will not be possible. "
There is risky before we complete download the target application and after use wl in mfg.test set SECURE_BIT.
Because this, I expect download the target application first. Then use the wl run in RAM to set SECURE_BIT at last.
I think you can understand my concern.
Regards!
Max

Hi ,
Actually the suggested process compromises the devices security.
So the current steps are secured, even if it is risky if we miss doing the steps properly.
Thanks,
