Hi All,


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.
