Hello,
We have run into an issue in our project where a DMA channel stops before it has finished a transfer.
Here are the configs for the DMA:
In top design:
In user app:
Now, I have this chunk of code in the DMA interrupt handler
This if statement is meant to trigger when we finish the final X loop, and restart the DMA channel. So, this channel is basically supposed to keep going forever until an external condition stops it.
We are currently running into a case where the DMA channel stops transferring data, and the callback function stops getting called.
I tried logging the value of the following variable:
I see this value change when I call DMA Enable or DMA Disable, and it also changes when the DMA channel finishes the transfer (if I don't re-enable it in the interrupt handler). However, if the DMA stops by itself, the value stays constant before and after the DMA channel stops working.
Any insights into this issue will be much appreciated. Let me know if you need more information from me.

Hi,
according to the 5LP reference manual the datapath outputs are registered, but it's also possible to use the combinational signal. Unfortunately, I can't find any information about how to enable the combinational output on the device.
For simulating the component, I figured out that it seems to be enough to override a parameter, e.g. so_sync, etc.
But I doubt that this is the correct way to enable combinational output on the PSoC device. Digging deeper into the device manuals shows that this feature seems to be bound to the corresponding UDB config register #8. The default value of this register within the component definition is 0x00.
But here the user can't know which bit is assigned to the output which should be combinational. So, how to correctly enable combinational output for datapath output mux?

When using the license key received for the UART & I2C plugins from your side.
The key seems to be activated on the EB Client license administrator but when adding those plugins to tresos, it gives an invalid license message.
Here is the response from EB side when I created a ticket regarding this issue.
It's just a license to open Eb Tresos Studio, to enable 3rd party MCAL from Cypress I suspect another additional license is required.
Please contact Cypress for further support.
Notes:
I wrote this issue in the discussion as I wasn't able to create a case.
The license is working on other machines but it’s not working on my machine.
Error messages are attached.

Hi
Good day.
I have a questions about single/dual bank selection on Traveo II.
We are based on programming guide to implement the programming algo.
it doesn't mention about bank selection, and it is mapped the single bank.
My question is..
if customer need to load the image file to dual bank mapping, do we need to bank selection option to set FLASHC_FLASH_CTL? or we don't need to do anything, and the device will do the bank setting after it is booted.
There is customer's requirement. You can see the file B setting. and How do we do?
Thank you.

I have to calculate the BAS16-02W reverse diode current for 10V at 25°C and 75°C. We can see from the data sheet the maximum values, see below.
I suppose, that on the date sheet graphs there are the typical values, see below:
The value of the reverse current at 25V and 150°C is 10µA compared to the 30µA of the max. value. Therefore, I suppose that we can find the maximum reverse current from the graph multiplying the found value by three. For example, at 25V and 75°C we found the Ir is about 180nA. Therefore the maximum value is about 180nA*3=540nA. On the other hand, from 25V to 70V Ir grows twice. I estimate, that from 25V to 10V the Ir will be twice lower, about 270nA.
Am I right?
But, when I am looking at the graph at 70V at 25°C I find 10nA current only, but on the data sheet there is 1µA max. current which is 100 times higher. Where is the catch?
Show LessHi Infineon Team,
We need to conduct Pre compliance test on CYW43455 BT chip on Android 11 for which we need Hcitool.
Could you provide us hcitool for android 11 along with the integration document.
Thanks,

I was wondering if you could provide die verification for one of your products, IRFB38N20DPBF. Upon exposing the die, the markings revealed 746625, 746636, 746647, & 746658. My question is are these markings correct for this device?
Our company does component authentication for a government prime contractor who requires to have the die markings match the external markings exactly or receive verification from the manufacturer.
I have included pictures of the component going through authentication testing and a picture of the die markings revealed post decapsulation .
Thank you in advance for any assistance that you are able to provide.

I used the CY_GPIO_Port_Init function (gipoport, config); but how do I write the data ?.
with PSOC 5 use: void portxxx_Write (uint8 value);
Hi,
I am working on a Denebola CX3 Kit which comes with a OV5640 image sensor. I used the sample application "Cx3UvcOV5640" and flashed the board. I am able to see the video on e-CamView and it works fine.
I would like to control a peripheral, other than the camera I2C, which is connected to CAM_I2C_SDA and CAM_I2C_SCL on the MIPI connector.
How do I configure it and transmit/receive to the peripheral ?
I see the API CyU3PMipicsiInitializeI2c() which should initialize the I2C interface. How do I transmit and receive to this I2C interface. Is there any MipiI2c transmit and receive APIs available? Any examples you can point to me will be really helpful.
Thanks and Regards,
Subbu
Show LessHi,
I am using CX3 based custom board, I have written my firmware image in SPI flash and my board is enumerating as a device in SPI boot mode. But image streaming is not being done(getting black screen).
My DMA and timer getting restarted continuously. I followed this KBA and changed the timer period and I increased the DMA buffer size. Still I am unable to get image in AMCap or Camera app.
Please find the below log for your reference.
Can you help me in this regard?
Thank you,
Shafi.
