Re: Submitting a patch for integrated usb-phy on stm32f723

Hi,
Had to do a small correction to the above patch.

Line 940 in os/hal/ports/STM32/LLD/OTGv1/hal_usb_lld.c changes,
from:
otgp->GCCFG = 0x00800000;
to:
otgp->GCCFG = GCCFG_PHYHSEN;

Sorry about that fellows.

Thanks,
AQ

Re: Is there an error report for USB packet retransmits

Thanks for the reply Giovanni, appreciate it. Pertaining to the same concern, let me ask another one. USB packets have a crc based on which packets are accepted or rejected.

Each thread has its own separate stack, so you need to give each thread enough space. This is the most critical thing when doing multithreaded embedded programming. Automatic variables are allocated in the function stack frame so if you allocate 4KB inside a function then all threads calling that f...

Is there an error report for USB packet retransmits

Hi,
I am using stm32f723 and as a usb cdc device. I was trying to see if there is any api available which gives me health status of my usb link. How many packets got dropped or retransmitted etc. Would you guys know of any such stats available?

Thanks,
AQ
