Problem with DMA and USART receiving problem

Hello,I have an STM32F107 microcontroller that uses DMA and USART to receive 250 bytes every 10 ms. The RTOS tick is 1 kHz, so osDelay(1) results in a delay of about 1 ms.The sender transmits 200 bytes every 5 ms, and during this phase, it is not cri...
