<pre>Zdravim,<br>
zacinam s ARM a GCC a narazil som na jeden problem. Ked som skusal debugovat, vzdy ked pridem na cyklus FOR debugger sa zasekne a pomoze az opatovne spustenie openOCD a arm-elg-gdb. Ked kod napalim gunguje ako ma aspon zda sa. Ked dam za for breakpoint, dam RUN a takto ho preskocim da sa v debugu pokracovat. Takisto mi je zahadou preco sa v primitivnej cakacej gunkcii<o:p></o:p></pre><pre><br>
<br>
delay(uint_32_t t){<br>
for(volatile uint32_t n; n < t, n++);<br>
}<br>
<br>
musi pouzut VOLATILE, okrem main() ju nikde nepouzivam. Skusal som vlastny kod, takisto aj priklady z tutorialu "Using Open Source Tools for AT91SAM7S Cross Development revision <o:p></o:p></pre><pre>2.pdf" problem bol vzdy ten isty. JTAG pouzivem FT2232, GCC a utility z balika WinARM 20070505, procesor AT91SAM7S... Prosim podarte aspon kde hladat problem, ja uz vazne netusim.<br>
