writing a word to cfm1 using on chip flash ip on max10

hii yes 

i write a 32 bit of data on avmm_data_writedata on the avalon bus , and i set the burstcount to 1

i hold the avmm_write<='1'  as long as waitrequest=1 , and when i receive waitrequest=0 i disable the  avmm_write , update the next address and move to the next data to write 

As noted earlier, write operations generally succeed when I verify the success flags in the CSR status register. However, I occasionally encounter a write failure when writing a 32-bit word, even though previous writes completed successfully.
