OSPI on EK-RA6M5

The project implements communication with the on-board OSPI flash on EK-RA6M5 in 2 different modes: SPI mode and Single OPI (SOPI) mode

The QSPI flash chip is Macronix 512 Mb (64 MB) Octal serial flash memory (MX25LM51245G):

The FSP module used on this project is r_ospi:

The code has the following functionality:

1st part (SPI mode):

1) Reset Octa-Flash

2) Erase sector 1 in SPI mode

3) Write data at 0x70001000 (sector 1)

4) Verify the written data in OSPI during debugging

2nd part(Single OPI mode):

1) Write Configuration Register 2 and enable DQS bit as per section 36.8.3 of RA6M5 hardware manual

2) Write Configuration Register 2 and set dummy cycles to 10 for SOPI (Table 9-3-1 on MX25LM51245G manual)

3) Write Configuration Register 2 and enable SOPI

4) Change protocol from SPI to SOPI on r_ospi

5) Erase sector 2 in OPI mode

6) Write data at 0x70002000 (sector 2)

7) Verify the written data in OSPI during debugging

STEPS to run the project:

1) Import the attached project into e2studio workspace.

2) Build and debug (download) the project on e2studio
