Hi, all.
Recently I downloaded the latest version of FlashMagic tool (version
5.74.2160) with secondary Ethernet bootloader example for LPC2300 included.The provided example of bootloader code is for LPC2364 and the example application (Blinky) is for LPC2378.
My custom board is based on LPC2368 and my final intention is to allow in-field firmware upgrade using Ethernet link, when the secondary bootloader will be invoked from application level using an IAP call.
Now, before trying to run the examples provided with FlashMagic installation, I changed them as follows:
- In 'Options for Target'->'Device' I picked the LPC2368.
- In 'Options for Target'->'Target' I set the IROM1 size to 0x80000
- In the sbl_config.h file I enabled the 'Ethernet Debug' mode and disabled the 'Activity Indication Led'
- Instead of using a led for bootloader activity indication, I put a several printf calls right after init_serial() in the Blinky's main routine.
After both projects were re-built (using Keil compiler), I loaded the bootloader HEX file using FlashMagic tool via serial connection. When finished, I re-powered the board and then loaded the Blinky's HEX via Ethernet connection, which gave me an indication that the secondary ethernet bootloader is functioning.
Later, I re-powered the target board again in hope to see any indication of Blinky's application activity , but got nothing. The HyperTerminal seems to be configured correctly - accordingly to how the UART is configured by the application.
Please advise what I miss. My main concern is why the application loaded using the secondary bootloader does not start.
Thanking you in advance. mb
