Dear SDCC users and developers, I'd like to use SDCC to compile some code
for a PIC14 enhanced core device, (PIC16F1936) This mcu is supported by recent
gputils, but apparently there is no support in sdcc.Because other similar
device (with same cpu core) is supported: 12f1822, i decided to patch sdcc to
support it. Now I have a problem, maybe not specific to the new mcu, but rather
generic problem: I tried to define config in the source file but have no
success. Pic14enh. devices has two config word at 0x8007 and 0x8008.I tried
with the following ways: First try:unsigned short __at(_CONFIG1) config1Reg =
(_FCMEN_OFF & _IESO_OFF & _BOREN_ON & _CPD_ON & _CP_ON & _MCLRE_OFF & _PWRTE_ON
& _WDTE_OFF & _FOSC_HS);
// This compiles without error but results _no_ value at address 8007 in
resulting hex file Second try:
__config __at(_CONFIG1) config1Reg = (_FCMEN_OFF & _IESO_OFF & _BOREN_ON &
_CPD_ON & _CP_ON & _MCLRE_OFF & _PWRTE_ON & _WDTE_OFF & _FOSC_HS);
// This gives a compile time error: syntax error: token --> '__at'
Third try:
// Trying to have both config1 and config2:
unsigned short __at(_CONFIG1) config1Reg = (_FCMEN_OFF & _IESO_OFF & _BOREN_ON
& _CPD_ON & _CP_ON & _MCLRE_OFF & _PWRTE_ON & _WDTE_OFF & _FOSC_HS);
unsigned short __at(_CONFIG2) config2Reg = (_LVP_ON & _BORV_25 & _STVREN_ON &
_PLLEN_ON & _WRT_ALL);
// Linker says: Multiple sections using address 0x8008
So, I did not have success to specify config values.The resulting hex file
never contains any values at 0x8007 and 0x8008. I browsed the sdcc doc, but did
not found how to specify config for pic14enh devices.Could you please help?
Best regards,Tamas
