Text syas "For example, in Figure 2.4, resistor R39 has a value of 680 ohm". In fact both resistors labelled as R39 in figure 2.4 have a value of 33 ohm (shown in diagram as 33R) - this is also probably an error, it is certainly unusual for a circuit diagram to show two resistors with the same identifier (unless the resistor is part of a pack, in which case the diagram would show which part of the pack is used).

After:
(in minicom)
RedBoot> load -x modem

CTRL-A Z to get Minicom Command Summary.

Choose S to send files.

[Upload] Choose xmodem.

Use arrow keyes and space (possibly need to hit space twice) to navigate to blink.exe in your
directory structure. Select blink.exe and hit Enter. This begins the trasfer. If all goes well, you
see:

┌───────────[xmodem upload

And then, beneath:

RedBoot> load -m xmodem

which you had typed earlier, you'll see:

CEntry point: 0x00400180, address range: 0x00400000-0x004001d4
xyzModem - CRC mode, 28(SOH)/0(STX)/0(CAN) packets, 5 retries

PS: I'm using gcc-4.2.1

This is not an error, but a suggestion to include the suggestion to:

set remotebaud 115200

in GDB. It helped fix some unrecognized packet/connection timed out kind
of error I was having (but unfortunately now I am not able to reproduce the problem).
