Наткнулся на ляпу то ли в кремнии, то ли в линкер-скрипте - либо не работает, либо не с тем линкер-адресом прописан в скрипте регистр подтяжек CNPU1 - не включает подтяжки на ногах RB0..5/RE6..7 (т.е. на CN0..7). В скрипте только для этих dsPIC30 CNPU1 прописан по 0x0064, в то время как для остальных - 0x00C4 (тоже пробовал - не помогает). На других (не SMPS) dsPIC30 все работает как надо.

Кому не лень - прожгите, пожалуйста, вот этот код (HEX - ниже) и гляньте, подтягиваются ли RB0..5 и RE6..7.

Код:

__30F2020	= 1
.include	"p30f2020.inc"
.global __reset

.section	.text
config	__FBS,NO_BOOT_CODE
config	__FGS,CODE_PROT_OFF

config	__FOSC,CSW_FSCM_OFF & FRC_LO_RANGE
config	__FWDT,FWDTEN_OFF
config	__FPOR,PWRT_128
config	__FICD,ICS_PGD1

__reset:
	setm	ADPCFG
	setm	CNPU1
	bra	$

.end	

HEX:
