Hello, could you help me with the information of the CYBT-213043-Mesh board on how to program it through J-Link?

Hey,

We are using CYRS16B512 in a design and because there is no footprint recommendation in the datasheet it is not clear if the pins come pre-bent or we need to mill out under the chip as the mechanical drawings are showing straight legs. Also many other ceramic packages have heatsink exposed pads, does this one? Hope someone can shed some light on this, i have not been able to find info about this in the datasheet

I am trying to program and configure the CYUSB4347 for 5V only operation.  When I update the FW with a composite image that has the PD Configuration that I need, the PD Controller is not being updated. Here is the output of the Get Status:

How can I get the PD Controller to update properly?

I'm using the CYUSB4347 HX3PD chip for a power delivery device.  The datasheet (page 12) shows that an embedded controller can interface with the HX3PD over the I2C_2  interface.  Is there a separate document for this i2c interface that includes register descriptions and available commands?

Hi

I encountered a problem while using AMUX to switch channel for 16 bit or higher resolution Delsig ADC.

I verify that in CY8CKIT-050 board and run the  example project as below show,  it can works as expected.

but when I change the ADC resolution to 16 bit, and input fixed voltage like half of power, the readout  is  abnormal of which jitter is serious,  I think the Amux cause that, so I increase the delay time before start ADC to keep enough time after change channel, no matter what long I delay, the problem is still exist. I am confused about this problem.

I hope someone can help me solve this problem,  thanks very much!

Best Regards,

Environment: PSoC Creator 4.4, CY8C4147AZI-S465

I'm going into the infinite IntDefaultHandler and seeing ENOMEM when calling srand() or rand() without heap.

Since I'm currently not doing any other dynamic memory allocation if I run the same code without calls to srand() and rand() the code runs fine, even without any heap.

Is it expected per the C standard?

I tried to run the exact same test of running srand() and rand() without heap on a TI F28002x and it runs fine, although of course rand() isn't actually returning a random number.

My fear is that srand() and rand() are unsafely using the heap in PSoC 4's implementation.

Hi,

I am currently using CY8C624ABZI-S2D44 (PSOC6) with DFU as APP0 and APP1 which supports USB-CDC UART based APP1 firmware update. Everything is working fine so far. But as I am expanding my application and need more FLASH memory as this PSOC6 comes with 2MB flash, I am unable to expand FLASH beyond 960KB and its unhappy when I tried to move FLASH_BOOT_META data inorder to allocate more than 1MB flash. Please refer this as my current “.ld” files configuration and provide valuable inputs on this.

flash_cm0p  (rx)  : ORIGIN = 0x10000000, LENGTH = 0x2000    

flash_app0  (rx)  : ORIGIN = 0x10002000, LENGTH = 0x10000

flash_app1  (rx)  : ORIGIN = 0x10012000, LENGTH = 0xFA000

flash_boot_meta   (rw)  : ORIGIN = 0x100FFA00, LENGTH = 0x400

We are trying to get the CY4163 working with an Avnet UltraZed-EV SK (Starter Kit), which consists of an UltraZed-EV SOM (System On Module) and UltraZed-EV Carrier Card. The UltraZed-EV SOM has a Xilinx Zynq UltraScale+ MPSoC (Multi Processor System on Chip), aka ZynqMP. The ZynqMP is running PetaLinux 2020.2. The UltraZed-EV SK works fine with the CY4609 and CY4603. However, the CY4613 is not detected when connected to the UltraZed-EV SK. Nothing appears under lsusb or dmesg. To rule out an issue with the CY4613, it has been tested with a desktop Ubuntu system where it works fine.

What could be causing this behavior and how might we fix it? Thanks in advance.
