Hi Greg,
Thanks for your important message.
I do check the byte order. It seems that my config file is set correctly.
After analyse the pcf file, i found the point.
The pcf font files I use on arm board is from my PC ,Fedora 5. The files
seems that the byte order differs between the front header part and the
latter parts. And engine/font_pcf.c fails to deal with that situation.
For example,
helvB18-ISO8859-1.pcf,
format = readLSB32(file); //the format is got is 00 00 00 0E
endian = (format & PCF_BIT_MASK)? PCF_LSB_FIRST: PCF_MSB_FIRST;
num_glyphs = readLSB32(file);
// The value should be 00 00 00 C0, however after readLSB32, i got C0 00 00
00. it is wrong.
This is the reason of why my ARM system crashes.
Thanks
Max
