"Initialize the hardware" section |
In Chapter 2, under "Initialize the hardware" section below text is mentioned:
As per above text, address 0x00000000 belongs to flash memory on the Arcom board.
But in Chapter 2, under "Examine the Landscape" section below memory map has been mentioned.
As per above memory map, address 0x00000000 belongs to SDRAM on Arcom board.
The text mentions address 0x00000000 as flash memory but memory map mentions it as SDRAM memory. Both are not aligning with each other. Request you to provide resolution on this issue.

ist paragraph |
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).

RedBoot (Section); minicom setup. |
(This is not an error). I used this page for my minicom setup:

File transfer using minicom on Linux is not covered. |
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
- Press CTRL-C to
quit]────────────┐
|Retry 0: NAK on sector │
│Retry 0: NAK on sector │

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

GDB Connection Problems |
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).

source code: memtestAddressBus |
I believe the function memtestAddressBus() contains two misleading source code comments:
The code section labelled with "Check for address bits stuck high" does not only detect "stuck high" errors, but also detects "stuck low" errors (because both errors result in aliasing of a non-zero address with address 0).
The following section, labelled with "Check for address bits stuck low or shorted", cannot detect "stuck low" errors (because it does not check address 0), but instead only checks for "shorted address line" errors.

Second line |
Second line reads:
TIMER_STATUS = TIMER_0_MATCH;
There is no reference to register TIMER_STATUS on page 37 where others registers are defined. After reading many pages of this book, I found:
//resources.oreilly.com/examples/9780596009830/-/blob/master/chapter8/timer.c
which states correct line as:
TIMER_STATUS_REG = TIMER_0_MATCH;
So, when will you correct the error on page 161?

Figure 10-5, list item 6 |
I believe that list item 6 should read: "The operating system scheduler code exits.", not "...scheduler code exists."

3rd Paragraph |
Today's (4-10-08) price for the VIPER-Lite Embedded Linux Development Kit is US$598.00 including discount. I was concerned the Arcom rep and I were not talking about the same product until I checked back on the review page for this book and saw an anonymous reviewer who was quoted full boat of $997.00.
May I suggest in the next printing you change "$295 (plus shipping)" to "40% discount".
