Ya probuyu napisat' boot loader s flasha.
Vsyo by nichego no mne nuzhno pomestitsya v 1 KB. S drugoi storony ne xochetsya na assemblere i vot nikak ni poymu pochemu stack ne popodaet tuda kuda nado.

-stack 0x400
MEMORY {
BOOT : origin = 0x0000, len = 0x00600
ISRAM : origin = 0x0600, len = 0x1000
ISRAMSTACK : origin = 0x1600, len = 0x2000
SDRAM : origin = 0x80000000, len = 0x2000000

}

SECTIONS {
.vectors {} > BOOT
.const: {} > BOOT
.text: {} > BOOT
.bss: {} > ISRAM
.stack: {} > ISRAMSTACK
.far: {} > ISRAM
.sysdata: {} > ISRAM
.sysregs: {} > ISRAM
.sysinit: {} > ISRAM
.cinit: {} > ISRAM
.data: {} > ISRAM
}

vot cmd file. Etogo ne dostatochno shtoby stack pri compilyacii popal po naznachennomu adresu? Ne obrashayte vnimaniya shto seciya stecka bol'she razmerov real'nogo stecka... eto prosto straxovka na budushee.

A kuda popal posle kompiljacii stack ?

Etogo .cmd fajla dostatochno, chtoby sekcija .stack popala tuda, kuda nado. Eshchje nuzhno inicializirovat' SP (t.e. B15), no eto dolzhen avtomaticheski sdelat' c_int00.

Ya rabotayu bez RTSliba i _c_int00 prosto pered mainom pastavlen. Stack voobshe ne inicializiruetsya. Te privyazyvayetsa k B15 i beret znacheniye kakoye tam est'.

bars · Aug 11, 2004, 14:25

Togda neponimaju, o chem vopros. Inicializiruj B15 i budesh' imet' stack tam, gde xochesh'.

veg · Aug 11, 2004, 15:07

OK

Ya tak i delayu esli chestno.
No ya xotel programmu napisat' v C bez assemblera. A shtoby u etogo registra pomenyat' adres prixoditsa asmovski kusochek tuda zapyxnut'.
No ya nachinayu ponimat' shto bez RTS liba na C pisat' nel'zya, navernoye

Po moemu chto-to vrode

asm(" mvk 0x2000, B15");
asm(" b _main");
asm(" nop 5");

ne tak uzh i slozhno ;-)

Spasibo

Ya eto tak i sdelal. No xotelos' shtoby comiler dislociroval
