Using WICED Studio 6.2.1 with a CYW43907. There are a number of unused features that I would like to remove, to make the codebase lighter. E.g. buttons, audio, etc. Short of going thru the whole SDK and manually removing code, there does not seem to be any way of disabling these features. I tried setting PLATFORM_AUDIO_NUM_INPUTS to zero but then it creates compile errors with zero indexed arrays, etc.
Is there a good way to remove these features?
Show LessIs there any documentation on programming OTP memory over JTAG instead of using mfg_test and the wl app?
The suggested process from AN214842 adds ~1 minute to our programming cycle.
Show LessBased on OpenOCD -WICED and CYW943907AEVAL1F JTAG Header , I need to install libusb drivers to use Segger JLink. Thsis may nto be possible with all the PCs we are using.
Can someone suggest a different JTAG adapter that is supported by Wiced Studio without adding libusb drivers?
The target device is CYW43907 1GC.
thank you
Show LessI need the pinout to connect a standard JTAG/SWD adapter (in my case Segger JLink) to the CYW943907AEVAL1F.
I can see a picture of the Olimex JTAG with jumpers in the "CYW943907AEVAL1F Evaluation Kit User Guide" and also in OpenOCD -WICED. BUT those jumpers go to more than the JTAG header (it also goes to J9) and there is no documentation of the pins.
Please let me know all pins that need to be connected to make JTAG work.
(this was originally asked as CYW943907AEVAL1F JTAG Header but that post turned into a discussion of JLink drivers)
Show LessI have a product that has the cyw43438 Bluetooth module in it. It is advertised that as 4.2 but is it capable of having DLE (Data Length Extension)?
Show LessIm looking for some guidance to modify the existing OTA2_example files shipped with WICED to run without a console. I'm hoping that I can get the system to navigate to an IP/filename that is static. Can someone familiar with the OTA2 system point me to the modifications I can make so this system can be integrated into my app? Thanks.
Show LessCan I use CYW43907 without external SFLASH?
For example. refer below.
CYW43907/CYW54907 Product Guide
In Block Diagram, Application MCU SubSystem has ROM(640KB).
Can I use this ROM(640KB) instead of external SFLASH?
If so, how can I do that?
Show LessHello:
Is there any examples on how to define/use ISRs in WICED for microsecond level sampling? This has been asked many times in the forum, but the only answer is to use the rtos_delay_microseconds() function. This method wont work for fixed sampling rate applications as there is a chance that function takes much longer than the passed time to return.
app info: every 5 usec I want to do a spi read to take an adc sample to achieve a sampling rate of 100khz. Im lloking for an example that defines a timer interrupt and how to use it. Thanks.
Show LessThe JTAG Header on the CYW943907AEVAL1F seems non-standard. Has anybody found a cable to connect a standard JTAG adapter to this header? The UG shows an Olimex with separate wires for each signal but I cannot find that breakout anywhere. Short of making my own, does anybody know how to connect to the header?
Also, the only thing I need to do is to flip the switches to move JTAG to the header, right?
Show LessNot sure if this is the right thread, anyway... I have to replace a BCM43455 integrated chip from a mobile circuit board, and i want to know how many air flow heat can i apply to remove the chip without damaging it, the air flow speed recommended, finally, what is the maximum exposure time for that?
Thanks in advance.
