Summary

0000060: vfs_fseek and vfs_write fails and crashes ethersex

Description

For testing of "vfs_fseek" and "vfs_write" I created a ECMD called "file write"
with two parameter "filename" and "value"

while calling vfs_fseek or vfs_write, ethersex crashes (most time with reboot) like this weather i2c-EEPROM or SD-Card is activated and connected

file write bla foobar
D: file: bla handle: 128
D: debugging enabled
D: disabling watchdog
D: booting ethersex firmware 0.2...

Additional Information

int16_t
parse_cmd_file_write(char *cmd, char *output, uint16_t len)
{
char filename[8];
  char value[50];
  sscanf_P(cmd, PSTR("%s %s"), &filename, &value);

  struct vfs_file_handle_t *fh;

  fh = vfs_open (filename);
  debug_printf("file: %s handle: %i\n",filename, fh->fh_type);
/*
  vfs_fseek (fh, 0, SEEK_END);
  debug_printf("seek done\n");
*/
  vfs_write (fh, value, sizeof(value));
  debug_printf("written\n");
}
