U599 + W25Q64 Flash QUADSPI External Loader Errors

Referring to AN5050 as well as an online guide for creating a QuadSPI loader for a W25Q32 flash IC, I have written code for a W25Q64 flash IC that I am interfacing in QuadSPI mode using the OctoSPI peripheral on the U599.When I try reading the flash ...

OPTVERR bit seems to be erroneously set, why?

We are seeing a situation where the OPTVERR bit is unexpectedly set after power reset. We've checked and all the complement words in the Flash area for the option bytes are set correctly, so no corruption there. The description in the reference manua...

UART Rx Interrupt Routine for Variable-Length Data on STM32F072RBT6

The microcontroller sometimes cannot receive TCP data

Hi.In my system, the opposing device sends TCP data at 20ms intervals,and the microcontroller receives the TCP data non-blocking at 20ms intervals.Therefore, the ethernetif_input() function of LWIP is supposedto be called at 20ms intervals and store ...
