We are developing from scratch our board
- At this moment we already powered the iMX233 and configured it to boot form SD card
- We connect our board to a PC via USB and change the value of HW_OCOTP_ROM0 to 0X00200008
- We created the SD Card image using Olinomex development Kit and test it in this board and runs ok
- We connect a logic analyzer to check the serial output pin126 from iMX233 and obtain the following output
U-BOOT 2017.01 (MAR 30 2017 – 17:48:18)
CPU: Freescale i.MX23 rev 1.4 AT 454 MHZ
Boot: SSP SD/MCC#0
DRAM: 64MiB
MMC: MXS MMC: 0
*** Warning – bad CRC, USING DEFAULT ENVIROMENT

NET: net initialization skip

Hit any key to stop autoboot: 3
Hit any key to stop autoboot: 0
=>
Our question is: “Why the boot process is stopped?” because in the development board the same SD card give us the following output
Hit any key to stop autoboot: 3
Hit any key to stop autoboot: 2
Hit any key to stop autoboot: 1
Hit any key to stop autoboot: 0 (why in our board jump from 3 to 0 so fast)
Switch to partitions #0, OK
