Hi

I'm currently having trouble trying to debug on a EZ-USB FX3 SDK. I have followed the instructions in the user guide but nothing seems to make it work properly. I am using a Olimex ARM_USB_TINY_H on the ARM and OlimexODS version of OpenOCD 0.6.1 with the Cypress EZ USB Suite version of Eclipse. (This is the only verison of OpenOCD that seems to work)

I am using the configuration file for the debugger from the OlimexODS package which was downloaded from their website, along with the arm926ejs_fx3.cfg in the files provided with the FX3 SDK which I modified to work with ftdi interface. I will attach them.

When I connect, I get a lot of warnings and errors in the console - also see attached file.

When the Eclipse debugger loads, I am stuck in the CyU3PFirmwareEntry. I have no options to step, and when I run it does nothing except stay at CyU3PFirmwareEntry. I believe it's supposed to run to main and break there but I am not seeing this. (Screenshot attached)

Any help is greatly appreciated and let me know if you need any more information that I might have missed.

Thanks.

Hi!

We have for a customer designed a camera system based on the FX3 and the AN75779 sample code, with minor modifications.
Our customer reports that sometimes the FX3 stops streaming and gets non-responsive.
Restarting the software on the PC sides does not help.
Rebooting the PC does not help.
The only thing that helps is powercycling of the FX3 (either by unplugging and again plugging in the USB or by powercycling of the PC)


SInce this application is running remotely and not supervised, powercycling is not possible with the current design.
We have not yet been able to do any logging when this happens, but have in the meanwhile some questions.

Are there any know problems with the AN75779 implementation that could lead to this kind of sympthoms?
(We have implemented a watchdog in the FX3 that should restart the FX3 if asserted)

Is there some reset handling for the USB interface implemented in the An75779?
I think there are eset USB messaged sent to the FX3 - is that something that the FX3 will act on?

I have some questions about the Infineon CO2 monitors I was hoping to get answered: 

SPEC: 

The CCG5 has power supply inputs at V5V_P1 and V5V_P2 pins for providing power to EMCA cables through
integrated VCONN FETs. There are two VCONN FETs in CCG5 per Type-C port to power CC1_P1/P2 and
CC2_P1/P2 pins. These FETs can provide a minimum of 1.5 W on the CC1 and CC2 pins for EMCA cable

(1). if V5V_P1 is 5V,

does it mean the Vconn Source is 1.5W / 5V = 0.3A ?

and configuaration - Vconn OCP setting is threshold = 30% , Debouce period = 1ms 

does it mean Vconn OCP trigger point is 0.3A x 1.3 = 0.39A and debouce = 1ms 

(1). if V5V_P1 is 3.3V ,

does it mean the Vconn Source is 1.5W / 3.3V = 0.4545A ?

and configuaration - Vconn OCP setting is threshold = 30% , Debouce period = 1ms 

does it mean Vconn OCP trigger point is 0.4545A x 1.3 = 0.59A and debouce = 1ms 

but SEPC :

In a notebook design, VCONN supplies power to the electronically marked cable attached to it. VCONN FETs on
CC lines can handle a current up to 0.5 A

it mean max vocnn ocp trigger point is 0.5A ??

Hi I,m using tc275 (Hightec compiler )and I have this error:

.bmhd_1 loaded at [80020000,8002001f] overlaps section .text

Any suggestions?

Thanks 

Hi All,

Does anyone knows the max voltage of XMC1302 GPIO can output?

In my PCB, I connected a Nmos Gate to XMC GPIO, Nmos Source to GND, Nmos Drain to another IC's Chip enable pin which has 4V (active high, pull this pin to logic low can disable the chip).

I want to control the IC's enable/disable. But when I pull up the GPIO, only about 0.9V I got. Can't reach the GS threshold voltage. (Min 1.0V, typ 1.75V)

Thanks.

I hope this is the right forum

Sorry if this is a simple question, I am new to this software. How do I build the C code provided in the C:\IFX_D2GL-HW-SW_V1.0.0\Firmware_Software\Communication Library\ComLib_C_Interface

I want to build the d2gl_basics application but I am unsure how to do this. Could anyone send some steps on how to do this?

Also another quick question, can I do this on a linux machine?

Cheers

1:i had found in the datasheet of BTS7200-2PEA, don't find that the inrush current description, So i want to know how i can know the inrush current that could be support by this chip ,  And how long time of the inrush current   

2: Another question,  i saw that BTS7200-2PEA, for the datasheet, There max Inom=1.2A,  So if i worked with 1.5A, How about the impact on the chip

Hi,

Now I use S25HS512T flash chip in our project, and need SDK for the chip of your product.

I have submitted download request, but that request has not been progressed. So I hope you can deal it early!

Thank you!
