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 18:24:26 +00:00
|
|
|
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

|
|
|
|
|
0x402bcc <gRadioTOCCal3_c+64>: 0x80009a00 0x8c90002f 0x00000000 0x00011194

2009-04-11 19:02:59 +00:00
|
|
|
0x402bdc <gRadioTOCCal3_c+80>: 0x80009a00 0x8c900000
|
2009-04-11 18:24:26 +00:00
|
|
|
|
|
|
|
|
then 4 entries from r5+24 (buffer_radio_init and cal5)
|
|
|
|
|
|
|
|
|
|
0x80009400 0x00000017
|
|
|
|

0x405230 <gRadioTOCCal5+8>: 0x8000a050 0x00000000 0x8000a054 0x00000000

|

2009-04-11 18:24:26 +00:00

SMAC_InitFromMemory(gRadioTOCCal1,40);

Some kind of success!
|
|
|
|
|
|
|
|
|
|
This replacment works:
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
// RadioInit(PLATFORM_CLOCK, gDigitalClock_PN_c, u32LoopDiv); // need this to work
|
|
|
|
|
|
|
|
|
|
/* my replacment for RadioInit, flyback and vreg have been separated out */
|
|
|
|
|
radio_init();
|
|
|
|
|
// SMAC_InitFromMemory(gRadioTOCCal1,40);
|
|
|
|
|
// *(volatile uint32_t *)0x80009000 = 0x80050100;
|
|
|
|
|
// SMAC_InitFromMemory(gRadioTOCCal2_24MHz_c,8);
|
|
|
|
|
// SMAC_InitFromMemory(gRadioTOCCal3_c,88);
|
|
|
|
|
// SMAC_InitFromMemory(gRadioTOCCal5,32);
|
|
|
|
|
// SMAC_InitFromMemory(gRadioInit_RegReplacement_c,344);
|
2009-04-13 13:55:35 +00:00
|
|
|
// SMAC_InitFromFlash(0x1F000);
|
2009-04-12 22:31:52 +00:00
|
|
|
// SMAC_InitFlybackSettings();
|
|
|
|
|
flyback_init();
|
|
|
|
|
// SMAC_InitFromMemory(gBuckByPass_c,16);
|
|
|
|
|
vreg_init();
|
|
|
|
|
|
|
|
|
|
*((uint32_t *)&u8RamValues) = 0x4c20030a;
|
|
|
|
|
fill_ram_struct(&u8RamValues);
|
|
|
|
|
|
|
|
|
|
for(j=0; j<16; j++) {
|
|
|
|
|
// buffer_radio_init[j] = get_ctov(j,u8RamValues[3]);
|
|
|
|
|
buffer_radio_init[j] = get_ctov(j,0x4c); //0x4c loads the right values into buffer_radio_init... but why isn't RamValues correct?
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Which means my radio_init, and vreg_init are good. It also means that
|
|
|
|
|
my intreprtation of buffer_radio_init is correct. It may also mean
|
|
|
|
|
that u8RamValues isn't important since I just set it's value.
|
|
|
|
|
|
|
|
|
|
That means I only have InitFromFlash to replace now!
|
|
|
|
|

Actually, I should test if that is necessary --- I still find it a
|
|
|
|
|
little hard to believe that they put essential data on NVM --- except
|
|
|
|
|
they could set codeprotect so that clods won't erase it on accident.
|
|
|
|
|
|
|
|
|
|
See PLM/LibInterface/NVM.h for some docs. Looks like they put a
|
|
|
|
|
standard SST, ST, or Atmel spi flash in there (note the comment about
|
|
|
|
|
continuous read mode).
|
|
|
|
|
|
|
|
|
|
MACPHY.a might use a ROM service for the flash init:
|
|
|
|
|
|
|
|
|
|
0000f97c g F *ABS* 00000000 InitFromFlash
|
|
|
|
|
|
|
|
|
|
ac: 4668 mov r0, sp
|
|
|
|
|
ae: f7ff fffe bl 0 <GetInitTranslationTablePtr>
|
|
|
|
|
b2: 4669 mov r1, sp
|
|
|
|
|
b4: 780a ldrb r2, [r1, #0]
|
|
|
|
|
b6: 0001 lsls r1, r0, #0
|
|
|
|
|
b8: 20f8 movs r0, #248
|
|
|
|
|
ba: 0240 lsls r0, r0, #9
|
|
|
|
|
bc: f7ff fffe bl 0 <InitFromFlash>
|
|
|
|
|
|
|
|
|
|
uint32_t InitFromFlash(uint32_t nvmAddress, uint32_t nLength);
|
|
|
|
|
|
|
|
|
|
Which looks like InitFromFlash(0x1F00,?);
|
2009-04-12 22:31:52 +00:00
|
|
|
|
2009-04-13 13:55:35 +00:00
|
|
|
Good news! It doesn't look like InitFromFlash is necessary. It might
|
|
|
|
|
just be a hook for them to patch the init that is grabbed from rom or
|
|
|
|
|
something.
|
|
|
|
|
|
|
|
|
|
Checking if buffer_radio_init is important. If so, then I need to
|
|
|
|
|
figure out how it's used and, preferably, what it means.
|
|
|
|
|
|
|
|
|
|
So buffer_radio_init is necessary for their code to work. I'm not sure
|
|
|
|
|
if it is necessary for the radio of if it's necessary for there app.

Ok, rftest-rx and tx are working but the range isn't very good. I
|
|
|
|
|
suspect that InitFromFlash is a factory trim for each part. Since I'm
|
|
|
|
|
not doing that then the range and reliability are suffering. Getting
|
|
|
|
|
the NVM to work should probably be my next step.
