LPC2214 possible bootloader rev. 1.63 problem

LPC2214 possible bootloader rev. 1.63 problem

2004-12-17 by tsvetanusunov

Hi,

we have production run of boards with LPC2214 and LPC2294, these are 
our LPC+external memory header boards and LPC+external 
memory+ethernet boards.
On about 20% of the boards Philips ISP utility fail to program the 
code on speed above 19200. Everything seems like baudrate problem as 
if 19200 or lower speed is used ISP programs everything just fine.

chip info is:

LPC2294JBD144
CD2664	03
TS0434 A

PART ID - 84016915
boot loader ID - 1.63
XTAL freq - 1 474 600 Hz

I sent this info to Philips but they seems to not have time to reply 
(season Holidays are aproaching ;), so I wonder if anyone else have 
had the same problems? is there newer bootloader release which to fix 
these issues?


Best regards
Tsvetan

We experienced the same behavior when upgrading to 1.63 on the 2114.
Please let me know if you hear of a solution.
 
Thanks,

My chip says

LPC2214FBD144
CD2662  10
TSD435 A

Are this chips loaded with bootloader 1.63?

Thanks
Ezequiel

I experience this problem quite frequently on my 2114 board (1.63 
bootloader), especially at 115k baud speeds. Using a 14.7456 Mhz I 
expected updating to be at least hassle free at high bauds (2114 
user manual). However, the process tends to halt & fail somewhere in 
the middle. Normally I'd resort to retrying the update until it 
eventually completes. I'm having the success with 56k baud & below 
speeds and below, with less halts occuring at 56k. Keep me posted if 
u've found the cause of this problem.

Check out the Interrupt handling application note online. The code 
was built on ARM ADS1.2. This application note has the startup 
assembly code for the LPC.

Re: LPC2214 possible bootloader rev. 1.63 problem

2005-07-15 by markcrow

I just recently discovered that if your ISP tool (by whomever) fails 
at a higher baud rate it is probably because of three issues:

1. There is an error in the Philips LPC2xxx User Manual.  All 
commands sent to the bootloader do not require a C/R and a L/F; in 
fact only a C/R is required.  

2. If the ISP software validates all returned commands it will fail 
to compare, for instance, "Synchronized[c/r][l/f]OK[c/r][l/f]" which 
it expects after transmitting the command "Synchronized[c/r][l/f]" 
with "Synchronized[c/r]OK[c/r][l/f][l/f]" which it actually 
receives.  Obviously the bootloader sent the "OK[c/r][l/f]" when it 
received the C/R in the "Synchronized[c/r][l/f]" command and then 
received and echoed the L/F later. 

3. Bootloader response behavior in this case is transmit 
latency/inter-byte gap/baud rate dependent.

I do not know if this will be only a V1.63 issue and have sent an 
email to my Philips FAE regarding this whole problem.  I'll let 
everyone know what develops.
