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);

*((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!
