URL: <http://savannah.nongnu.org/bugs/?26755> Summary: boot.h and ATMega48 and missing SIGRD Project: AVR C Runtime Library Submitted by: racemouse Submitted on: Mon 08 Jun 2009 05:17:32 GMT Category: Header Severity: 3 - Normal Priority: 5 - Normal Item Group: Header files Status: None Percent Complete: 0% Assigned to: None Open/Closed: Open Discussion Lock: Any Release: 1.6.6 Fixed Release: None _______________________________________________________ Details: We tried to compile the boot_signature_byte_get() macro from avr/boot.h using a mega48. The compiler complained "error: 'SIGRD' undeclared (first use in this function)". Datasheet says about the bit 5 in SPMCSR: • Bit 5 – Res: Reserved Bit This bit is a reserved bit in the ATmega48P/88P/168P/328P and always read as zero. It can be worked around by manually defining SIGRD as 5 and therefore not a complete showstopper... _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?26755> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/
