I am interested in performing POST (Power On Self Test ) operation in u-boot. As soon as the system starts booting , it should perform some basic functionality Testing,
- Cache test
- Memory Test
- RAM test
- I2C test
- SPI Test
- Ethernet Test
- UART test
- Watch Dog Timer Test
Please let me know the changes required in U-boot Code to perform POST operation while System bootup.
You have to implement the required tests for your hardware (unless these already exist) and then enable them in your board config file; please see doc/README.POST for details.
BTW: running these tests always for each and every boot is probably a very bad idea, as some of these testes are pretty expensive in terms of time needed. Also, some may have specific requirements to the hardware configuration (like there must [or nust not] be network cable attached, etc.).
Best regards,
Wolfgang Denk
