hi
i modified ft232_prog to set the product, manufacturer, and power
settings of an ft2232h
it works, but if i do ftdi_usb_close i get a segfault about libc something
i basically did this:
unsigned char new[128] = {0,};
ftdi_init(&ftdi)
ftdi_usb_open_desc(&ftdi, ...)
ftdi_read_eeprom(&ftdi,old,...)
ftdi_eeprom_decode(ee.ftdi,old
// change some stuff on the eeprom
ee.libftdi.size = 128 // The size of the (external) EEPROM on my board
ee.libftdi.manufacturer = MY_MANUFACTURER;
ee.libftdi.product = MY_PRODUCT;
ee.libftdi.max_power = 150/2;
// create a new one
ftdi_eeprom_build(&(ee.libftdi),new)
ftdi_write_eeprom(&ftdi,new)
ftdi_usb_close(&ftdi)
the last command gives a segfault.
if i just quit it works ok
any clues regarding what i'm missing?
i'm using 0.17-1 on ubuntu 10.04 32bit
this is what i get from gdb:
__libc_start_main (main=0x80494fc <main>, argc=1, ubp_av=0xbffff224,
init=0x8049870 <__libc_csu_init>, fini=0x8049860 <__libc_csu_fini>,
rtld_fini=0x11e030 <_dl_fini>, stack_end=0xbffff21c) at
libc-start.c:258

in libc-start.c
