Welcome to the Infineon Developer Community

Hi, can someone give me an example of programming automatically with python(just like psoc programming just customized with python)? What I want to do is automatically detect the boards and program with hex file. Does an API exist or how should I go about it?

How should an SOA be altered for low temperature? At high temperature (above 25C), the SOA must be derated. Does the SOA increase at temperatures below 25C? Specifically looking at PN: irhna597260

Hi,

I've written a custom bootloader for the CYUSB3014-BZXC using the Cypress Boot API. We've been using this bootloader without issue for the past couple of months. However, someone recently plugged the board into a USB 3.1 host controller using a USB 2.0 cable. Upon doing so we discovered that in USB 2.0 mode the device stops responding to standard requests after being suspended and then resumed. The traffic on the USB bus was captured with an Ellisys EX350 and shows the following transactions:

1. get device descriptor (success)
2. set address (success)
3. get device descriptor (success)
4. get configuration descriptor (success)
5. get BOS ddescriptor (success)
6. get serial number descriptor (success)
7. get language ID descriptor (success)
8. get product descriptor (success)
9. set configuration 1 (success)
10. LPM transaction (success)
11. Suspended
12. Resume
13. get language ID descriptor x 6 (failure)
14. get manufacturer descriptor x 6 (failure)
15. get product descriptor x 6 (failure)

UART Debug message prints from the firmware show the following:

Initializing FX3 Boot Firmware 1.6
Boot FW Event: CY_FX3_BOOT_USB_IN_SS_DISCONNECT
Boot FW Event: CY_FX3_BOOT_USB_SUSPEND
Boot FW Event: CY_FX3_BOOT_USB_RESET
Boot FW Event: CY_FX3_BOOT_USB_RESET
Boot FW Event: CY_FX3_BOOT_USB_RESUME

Are there any special actions that the firmware must take when it receives CY_FX3_BOOT_USB_SUSPEND or CY_FX3_BOOT_USB_RESUME in order to get the FX3 to ACK the control requests that take place after the the suspend and resume operations?

We also seem to experience the same problem when running the application firmware (uses Cypress full API) when the device is plugged in with a USB 2.0 cable. The bus activity is similar:

1. get device descriptor (success)
2. set address (success)
3. get device descriptor (success)
4. get configuration descriptor (success)
5. get BOS ddescriptor (success)
6. get serial number descriptor (success)
7. get language ID descriptor (success)
8. get product descriptor (success)
9. LPM transaction (success)
10. Suspended
11. Resume
12. set configuration 1 x 3 (failure)
13. Suspended

So the same question applies for the application firmware: what steps must we take in firmware in order for control transfers to succeed after the device has been suspended and then resumed?

Some other information that you may find useful:

Operating system: Windows 10
Host Controller: Asmedia ASM3142
Hub: none

I appreciate any help you can provide.

Thanks,
Michael

Hello everyone,

after a lot of back and forth we have decided to use ModusToolbox as an alternative to PsocCreator. During the installation I already had the problem that my user folder contains a space (C:\Users\M. Zim>). So I installed everything directly on C:/. I then set the following environment variables as recommended in the installation guide:

CY_TOOLS_PATHS = C:/ModusToolbox/tools_3.0

CY_GETLIBS_OFFLINE_PATH = C:/.modustoolbox/offline/

CY_GETLIBS_CACHE_PATH = C:/.modustoolbox/cache/

CyManifestLocOverride = C:/.modustoolbox/manifest.loc

However, there is still a problem with the paths. When I open the ProjectCreator and the LibraryManager, I get the same error.

I hope the problem can be easily solved with another path variable.

Regards

Moritz

I am a new programmer, and am learning about the FX3 through the SuperSpeed Device Design by Examble book, currently i am trying to replicate the visual studio examples coverered in chapter 7 using the CyAPI.lib library to develop host aplications, but i cant seem to compile them in visual studio community 2022, i keep getting the same error and im not sure wether  im not linking the library properly or missing something else. i attached a screenshot of said error, can someone help me with this? please and thank you.

p.d. i am using windows 10

Can this eSIM security controller be driven by an open drain?  I've taken many measurements on the IO lines that show good waveforms operating connected to a cell module driver without a pull-up resistor.  I assume the internal eSIM memory has the equivalent of a pull up but I would like to get confirmation. 

Hi Team,

We are using below part in our design, kindly provide below part Step file for our reference.

BSL606SNH6327XTSA1 (Package: TSOP-6)

Thanks, and regards,

Hi,

I'm using the ETHCAT_SSC_XMC48 example and I tried to add the FATFS app and used code from the FATFS example project. Unfortunately, f_open only returns XMC_SDMMC_CMD_TIMEOUT_ERR, no matter what I do. SD mode, SPI mode, configuration shuffling, nothing works, I either get the same timeout error or I get a hard fault. DAVE APP validates the configuration but there is clearly something wrong with the resource usage. The FATFS example and the ETHCAT example both work fine in their own projects.

Hello,

We are using CYW43438 with our imx8mn android 9.0.0 2.3.4 project. We have the driver as dhd-android-1.363.125.17.The wifi module is working fine

In our dts file we have the declaration

&usdhc1 {
#address-cells = <1>;
#size-cells = <0>;
pinctrl-names = "default", "state_100mhz", "state_200mhz";
pinctrl-0 = <&pinctrl_usdhc1>, <&pinctrl_wlan>;
pinctrl-1 = <&pinctrl_usdhc1_100mhz>, <&pinctrl_wlan>;
pinctrl-2 = <&pinctrl_usdhc1_200mhz>, <&pinctrl_wlan>;
bus-width = <4>;
pm-ignore-notify;
keep-power-in-suspend;
non-removable;
cap-power-off-card;
/delete-property/ vmmc-supply;
mmc-pwrseq = <&usdhc1_pwrseq>;
status = "okay";

brcmf: bcrmf@1 {
reg = <1>;
compatible = "brcm,bcm4329-fmac";
interrupt-parent = <&gpio2>;
interrupts = <9 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "host-wake";
};
};

I have checked that the pin is connected in board properly. For testing purpose we are connecting the wifi to a mobile hotspot. After a while the when the device goes to sleep(CPU shutdown) we turn off the mobile hotspot but we dont see any interrupt coming from the wifi module in logs. Can you help us to figure out the problem

Hi,

We are using SLB9672 TPM module over SPI interface on our custom platform.  We are able to perform StartUp & SelfTest (full) for TPM device.

But I am facing issue while performing PCR_Extend. we are using tpm2-tss 2.2.3 stack to perform this operation.

Please find raw send command and response we are getting from TPM module. we are using SHA384 algo.
Send command:
80 2  0  0  0  51 0 0 1 82 0 0 0 0 0 0 0 9 40 0 0 9 0 0 1 0 0 0 0 0 1 0 C [Hash value of SHA384]
Response:
80 1 0 0 0 A 0 0 1 C3

I am getting response code 1C3. Not sure why I am observing this error. Can you please help to identify the root cause.?
