However, we will add the new names to the in-program (and hence
wiki) database so that this new information becomes public. Thanks for
the heads up, Victor.

by Michał Witek
Hi. I just successfully flashed SST49LF160C on a Wyse S10 terminal and
it works fine, so it looks like the chip is fully supported. I'm letting
You know, because there are some questions marks in "supported hardware"
table near this one.

Dual boot MCU
by Stuart Johnson
I have an MCU that can boot from two locations of it's flash. The flash
is 2097152 bytes, and the MCU will boot from location 0 or half way. So
I created a layout file, like so:
00000000:0000fffff bank0
00100000:0001fffff bank1
But flashrom is demanding the image to be written is the full 2097152
bytes. What am I missing?
flashrom -p .... --layout my_layout --image bank0 -w flash.bin
Error: Image size (1048576 B) doesn't match the flash chip's size
(2097152 B)!

Wont flash bios
by Frei Bjerkestrand
I have an ch341a programmer and an W25Q128.W Winbond Chip, im trying to flash
a custom bios where I just change the serial numbers. Flashing the backup bios works but
flashing any other roms ends up in an error mess. I have tried to just erase it with -E but with no luck.

So you are using a 1.8V converter between the programmer and the chip?
Regarding the original issue: If you can not change any bytes, I would
suspect the flash chip is write-protected. Check its datasheet, it is
likely pin 3 is somehow pulled low (write-protect pin is usually active
when low).
