Hello Arthur,
After I remove code from the functions in Zmod/baremetal/intc.c,the functionality of initializing ZmodADC has been consistently unusable.I've been trying to solve the issue of initializing the functionality of ZmodADC these past few days.This problem has been bothering me for quite some time.This is quite a strange question, I can't figure it out by myself, I feel like I still need some advice from you.Here's my main.c code.

And if I removed the initiate part of ZmodADC
uint8_t channel=0;
uint8_t gain=0;
size_t length=TRANSFER_LEN;
ZMODADC1410 adcZmod(ZMOD_ADC_BASE_ADDR, DMA_ADC_BASE_ADDR, IIC_BASE_ADDR, FLASH_ADDR_ADC, ZMOD_ADC_IRQ, DMA_ADC_IRQ);
uint32_t *acqBuffer;
adcZmod.setGain(channel, gain);
acqBuffer = adcZmod.allocChannelsBuffer(length);
adcZmod.acquireImmediatePolling(acqBuffer, length);
static char time_formatted[15];
uint32_t valBuf;
int16_t valCh;
float val;
int coo;
the code of can run successfully.
In my opinion, the Eclypse Z7 may have a certain procedure to confirm the normal execution of interrupt processes. When there is any abnormality in the interrupt process, other actions will not be executed. Of course, this is my observation based on experiments, which may not be accurate.
If you need any other information, please let me know. Thank you very much.
