Q529.1E LA
Problem solution.
When programming fails
•
Check in the NVM at address 0x1D02 (BadBlocksAmount).
This items is 2 bytes.
1. If, after programming the flashutil UPG, this value is
still the same as the one of the process NVM, then the
amount of bad blocks was bigger then described by the
flash manufacturer.
2. If the value is filled in, it has to be checked if it's not to
close the maximum amount possible.
3. If the value is low, no problem.
•
If mounting fails, it will be shown on the UART. This can
only be seen when industrial mode is disabled.
•
As the UART logs are disabled when in industrial mode, it
is always good to have a set (or minimal setup) where the
problem board can be tested in. In this way the problem
can be reproduced in the normal mode of the SWUPG and
the prints will be visible! The Industrial Mode cannot be
disabled when programming to see the output. This
will cancel the ongoing programming!
When startup fails:
•
When a crash happens (only in the TV application!) and is
followed by debug dump UART output, then a copy of the
dump can put on a USB stick
1. This can only be done in the TV application, so if the
TV application keeps on crashing there is no way to
copy the dump of the flash to a USB stick.
2. When the TV application has started up completely,
CSM can be entered by pressing 1, 2, 3, 6, 5, 4.
3. Then put the remote in DVD mode and press 2, 6, 7, 9.
4. The file Dump_seetypeplate_seetypeplate.bin can be
found now on the USB storage device. The
seetypeplate_seetypeplate will be filled in depending
on the type of set.
5. This .bin file can only be interpreted in a Philips
development centre. Please give this input to your
Philips Service contact person.

Compare the UART logging on the problem board/set with
a normal startup behaviour. Identify till which point the
logging reaches.
