one more doubt ,previously when i first got the luckfox pico , i connected the usb type c to pc and i unkowingly did the nand flash erase,but as per the spec of luckfox pico it doesnt have nand flash,does it matter ? is this erase which i did first,is now causing the issue to not to boot from sdcard?

tried with sdcard 4gb and 8gb of class 10,with the same image,but still the same result on uart "RKUART"

ok i have ordered the sdcard u have mentioned,the link u have given is for burning spi nand flash images right? shouldnt the link be this https://wiki.luckfox.com/Luckfox-Pico/L ... burn-image for flashing sdcard with image

i have attached the Luckfox pico picture of the module iam using ,and also the ubuntu image of luckfox pico from where downloaded the image,as per my understanding both are of matching versions

Tried flashing luckfox pico image on sandisk 16gb sdcard and also sandisk 32gb sdcard ,after inserting each sdcard the output on the uart terminal is same,if i dont connect sdcard also same output,how to proceed further anyother ways to debug
