MQX 2 SPI Channel Operate by DMA problem

Hi,

 

We use two spi channels, spi1: for display driver, spi2: for flash memory. All spi channel use DMA.

 

While send data from internal ram to flash memory by spi2 port, spi1 port operates properly, but  while send data from external ram connected by flexbus to flash memory by spi2, spi1 port stopped and never will be work until restart device.

 

We update LCD by spi1 every 200mS with 5040bytes data.

We write 512 byte data to flash memory every 200mS.

 

SPI1: use number 2, 3, 4, 7 pins.

SPI2: use number 140, 141, 142, 143, 144 pins

Device:  MK60FX512VLQ12

MQX version: 4.2.0
