- NAME: u2440mon.c
- DESC: u2440mon entry point,menu,download
- HISTORY:
- Mar.25.2002:purnnamu: S3C2400X profile.c is ported for S3C2410X.
- Mar.27.2002:purnnamu: DMA is enabled.
- Apr.01.2002:purnnamu: isDownloadReady flag is added.
- Apr.10.2002:purnnamu: - Selecting menu is available in the waiting loop.
- So, isDownloadReady flag gets not needed
- - UART ch.1 can be selected for the console.
- Aug.20.2002:purnnamu: revision number change 0.2 -> R1.1
- Sep.03.2002:purnnamu: To remove the power noise in the USB signal, the unused CLKOUT0,1 is disabled.
