LPC1812 - can't program

Has anyone used the LPC1812 part with LPCXpresso or FlashMagic?

I've spent a couple of days now trying to read and program brand new LPC1812 (two of them actually - both give same results). I believe it is a documentation/silicon error. Here are my experiments:

This is a custom board with a 12Mhz LPC1812 part on it. I have the ISP accessible.

Starting with a brand new part...

TEST #1
Enabling ISP and using FlashMagic:
CRP shows Level 1
Device ID is correctly read and returns the correct value
all other commands (including complete erase) FAIL

TEST #2
Enable ISP and using a Terminal (arrows are informational only):
--> ?
<-- Synchronized
--> Synchronized
<-- OK
--> 12000
<-- OK
--> U 23130
<-- 0
--> P 0 14 0     <-- prepare sectors 0-14 in bank 0 (supposed to be Bank A)
<-- 7                <-- invalid sector
--> P 0 14 1     <-- prepare sectors 0-14 in bank 1 (supposed to be Bank B, but 1812 doesn't have Bank B)
<-- 0                <-- success
--> E 0 14 1
<-- 0

Further...
R 436208380 4   <-- this is address 0x1A0002FC (CRP address for BANK A)
1                        <-- Error Invalid Command
R 452985596 4   <-- this is address 0x1B0002FC (CRP address for BANK B)
0                        <-- success and the uuencoded data below is FF FF FF FF
$________
1020

Based on this testing, I would say that either the 1812 ONLY has Bank B, (data sheet says ONLY BANK A) OR the ISP for this part is using the wrong number to access Bank A (1 instead of the documented 0).

Bottom line is that both LPCXpresso and FlashMagic seem to be using '0' for the bank number which of course fails. Is there an quick way I can modify one of the connection scripts/programming scripts for LPCXpresso to test this theory? I have already tried just modifying the FLASH base address in the memory configuration for the part. While that does correctly fix the linker output, it doesn't seem to have any effect on the SWD connection scripts or flash programming process. I still get:

Hi Robert,

Can you please send the package marking of both the chips ?

Thanks,

Hi Robert,

Looks like you have carried out a thorough analysis!
There were some early sample parts that had a configuration issue and shipped with Bank B Flash instead of Bank B.
Can you share the part markings so we can correlate?

Thanks,
Ken

Hi Rob,
Does debugger connect to target through SWD connector?

Hello Ken,

I think we have the same problem as Robert.

We also use the LPC1812JET100.

Markings on the chip:

LPC 12812 JET 100
PMB 607.00 03
ESD 13050-

Data provided by Flash Magic:

Device ID: 0xF00BDB3F
Bootloader version: 12.1

*Addition: Both JTAG and SWD do not work for me.

With kind regards,

Rik

It wasn't, but it will now. I originally had DBGEN pulled LOW which is for boundary scan JTAG. It is now pulled high so debug should work correctly. I am now able to erase the part using the SWD port, but I still cannot debug. I'm using the Flash Driver: LPC18x7_43x7_2x512_BootB.cfx

I keep getting an error about a timeout programming sector 15 (of course the LPC1812 only has sector 0-14).

Why are you using the wrong flash driver? Surely you should be using the default (LPC18x2_43x2_512.cfx).

Re-read the thread. Apparently this batch of LPC1812 has the flash in BANK B, not BANK A. The default driver assumes the BANK A. The driver specified is similar, but uses BANK B.
