  This demo is based on the GD32H759I-EVAL V1.0 board, it provides a description of OSPI 
read and write flash with 1&8 lines in indirect/memory mapped mode,  The access result 
will be printed by COM. 
  After system start-up, print some related information and read the id of the flash.
If the id is not equal to GD25X512ME_ID, print the fail information. If not, write and 
read data from the flash. Then check whether the rx_buffer1/rx_buffer2/rx_buffer3 and 
tx_buffer1/tx_buffer2/tx_buffer3 are the same and print the result after that. 

  On the GD32H759I-EVAL-V2.0 board, LED1 connected to PF10, LED2 connected to PA6.
  
  JP68 must be fit USART, JP50, JP66 must be fit to LED, JP61 must be fit to OSPI.
