Entries in ram are processed by SMACinitfrommemory and executeentry
|
|
|
|
|
(which does the work). I suspect that these entries are loaded in from
|
|
|
|
|
the rom from the rom_data_init call in the beginning stub. For now
|
|
|
|
|
we'll do the simple thing of performing the actions they do, but for
|
|
|
|
|
real it would be better to load out from ROM and execute the entries
|
|
|
|
|
in a similar way. That way, if the cal data changes in the ROM, our
|
|
|
|
|
code should still work.
|
|
|
|
|
|
|
|
|
|
When radioinit first starts it seems to do checks for a 24MHZ clock
|
|
|
|
|
and if the buck should be enabled. Assuming 24MHZ and no buck the next
|
|
|
|
|
things it does is 5 entries in cal1 (40 bytes, 4 bytes per word, = 10
|
|
|
|
|
words, 2 words per entry = 5 entrys)
|
|
|
|
|
|
|
|
|
|
0x80003048
|
|
|
|
|
0x00000f78
|
|
|
|
|
|
|
|
|
|
0x8000304c
|
|
|
|
|
0x00607707
|
|
|
|
|
|
|
|
|
|
the next entry is zero addr with val 0x000161a8... this is a delay
|
|
|
|
|
entry. Loop here 0x000161a8 times. then return.
|
|
|
|
|
|
|
|
|
|
0x00000000
|
|
|
|
|
0x000161a8
|
|
|
|
|
|
|
|
|
|
Then two more memory stuffs:
|
|
|
|
|
|
|
|
|
|
0x8000a050
|
|
|
|
|
0x0000047b
|
|
|
|
|
|
|
|
|
|
0x8000a054
|
|
|
|
|
0x0000007b
|
|
|
|
|
|
|
|
|
|
then it seems like the emulator dies on the stack munging they do at
|
|
|
|
|
the end of InitFromMemory... but I think I've decoded the entry
|
|
|
|
|
enough to figure out the rest.
|
|
|
|
|
|
2009-04-11 20:24:26 +02:00
|
|
|
then they do one entry of r4 base + 48 (gRadioTOCCal2_24MHz_c[0])
|
|
|
|
|
|
|
|
|
|
0x80009000
|
|
|
|
|
0x80050100
|
|
|
|
|
|
|
|
|
|
then they do 11 entries in cal3 and reg replacment (first two have delays)
|
|
|
|
|
|
|
|
|
|
0x402b8c <gRadioTOCCal3_c>: 0x80009400 0x00020017 0x80009a04 0x8185a0a4

0x402b9c <gRadioTOCCal3_c+16>: 0x80009a00 0x8c900025 0x00000000 0x00011194

|
|
|
|
|
0x402bcc <gRadioTOCCal3_c+64>: 0x80009a00 0x8c90002f 0x00000000 0x00011194
|
2009-04-11 21:02:59 +02:00
|
|
|
0x402bdc <gRadioTOCCal3_c+80>: 0x80009a00 0x8c900000
|
2009-04-11 20:24:26 +02:00
|
|
|
|
|
|
|
|
then 4 entries from r5+24 (buffer_radio_init and cal5)
|
|
|
|
|
|
|
|
|
|
0x80009400 0x00000017
|
|
|
|
|
0x405230 <gRadioTOCCal5+8>: 0x8000a050 0x00000000 0x8000a054 0x00000000

0x405240 <gRadioTOCCal5+24>: 0x80003048 0x00000f00
|
|
|
|
|
|
|
|
|
|
then 43 entries from r4+152 (reg replacement)
|
|
|

2009-04-11 20:24:26 +02:00

then flash init. (hrmm.. this might be important)

2009-04-11 16:37:08 +02:00
|
|
|

2009-04-11 20:24:26 +02:00

then flyback init.

2009-04-11 20:24:26 +02:00

then maybe buckbypass sequence... 4 entries from r4+16
