How to verify the LPC54114 SPI ISP from the host. I am planning to imx8 as my host.
- I've put my LPC54114 in ISP SPI mode by pressing ISP0 and ISP1.
- Should I need to write a proper c programming to code to send the SPI ISP commands?
- Is there any utility like echo "0xA1" > /dev/spidev0.1 can be used?
- I tried to send echo 0xA1 and the response from LPC is always 0xFF
Please share the right procedure to verify the ISP over SPI.
