Hi, Thanks for the post. I noticed some peculiarities in the latest version specially regard to FLASH section. The compiler is throwing out errors when PROGMEM attribute is provided. unsigned char PROGMEM P_gu8_nlup[] dvr.c:205:40: error: variable 'P_gu8_nlup' must be const in order to be put into read-only section by means of '__attribute__((progmem))' The error clears if 'const' is placed before 'PROGMEM'. unsigned char const PROGMEM P_gu8_nlup[] Wondering whether there is any change in the latest version. Thank you. Nayani
