i want update my MOI Box Firmware from the Version 1.0 to Firmware_V2.0.2
2. from V1.x to V2.0.2
1) Connect RS232 serial cable & install software.
Connect one end of the RS232 cable to MOI, the other end to your PC, install the software:
- for Windows users: TTERMPRO
- for Linux users: minicom
2) Update through micro SD card*
Prepare a formatted micro SD card, copy the file “MOI290-fs.bin” into it, insert it into the SD card slot on MOI, power on MOI, "Enter" uboot quickly (within about 3 seconds after MOI is powered on) and input the command lines:
setenv loadmmcfs 'fatload mmc 0:1 40000000 MOI2900_fs.bin'
setenv updatekfs 'nand erase 50c0000;nand write.yaffs 40000000 50c0000 ${filesize}'
save
then input "re", MOI will start to update.
I want Update through micro SD card, bu I doesn't understand this Part:
"Enter" uboot quickly
How does i can enter uboot quickly ???
