如果传输计数超过70，PSoC 5lp DMA将被卡住

我使用PSoC 5LP DEV套件CY8CKIT-050，我附上了我的项目。我试图连接DMA到ADC，这样我就可以做一些高速采样。DMA和ADC按预期运行，直到BuffelySosig＝34（AKA从ADC获取34个数据读数并存储到RAM）。然而，当我将BuffelyStand设置为35或以上时，我永远不会到达DMAIONDOEYISR中断。DMA一次可以处理多达4095个字节，并且缓冲区大小为35，它应该只移动70字节到内存。有什么想法吗？

Im using the PSoC 5lp dev kit CY8CKIT-050 and I've attached my project. I am attemp ting to connect DMA to an ADC so that I can do some high speed sampling. The DMA and ADC are acting as expected up to BUFFER_SIZE = 34 (AKA taking 34 data readings from the ADC and storing to ram). However when I set BUFFER_SIZE to 35 or above, I never reach the DMA_done_isr interrupt. The DMA should be able to handle up to 4095 bytes at a time and with a BUFFER_SIZE of 35, it should only be shifting 70 bytes to memory. Any thoughts?
