Is there a limitation on the buffer length parameter to HAL_ADCEx_MultiModeStart_DMA? Length 32767 * 2 is OK and gives HAL_ADC_ConvHalfCpltCallback and HAL_ADC_ConvCpltCallback interrupts but 32768 * 2 fails with no interrupts.

I use STM32H753IITx and there is space in RAM_D1 to use length 2*65536.I call like this: if (HAL_ADCEx_MultiModeStart_DMA(&hadc1, guiaAdc12Data, (uint32_t)(ADC12_MAX_COUNT * 2)) != HAL_OK) { Error_Handler(); }
