steps 100 (boot) // same as i170

Code: [Select]

#define NUM_FL      101 
#define NUM_DATA    1   
extern int focus_len_table[NUM_FL*NUM_DATA];

// Conversion factor lens FL --> 35mm equiv
// lens      35mm     CF
// ----      ----     --
// 4.5         25      ( 25/4.5) * 45 = 250  (min FL)
// 54          300     ( 300/54) * 45 = 250  (max FL)
#define CF_EFL      250
#define CF_EFL_DIV  45

I don't know why it doesn't work.

Let´s expect similar problem at Ix285:

Quote

#define NUM_FL 551
#define NUM_DATA 1
extern int focus_len_table[NUM_FL*NUM_DATA];

// Conversion factor lens FL --> 35mm equiv
// lens 35mm CF
// ---- ---- --
// 4.3 24 ( 24/4.3) * 43 = 240 (min FL)
// 129 720 (720/129) * 43 = 240 (max FL)
#define CF_EFL 240
#define CF_EFL_DIV 43

const int zoom_points = NUM_FL;

I played with the num_data setting up to 5 & 6.
EFL gets stretched to either 275 or 325(!) this way, never 300.
Any sense here?

SVN commit 5418 fixes finsig_dryos to correctly find the 'focus_len_table' address for the IXUS275 (and the IXUS170 and IXUS285).
SVN commit 5419 fixes the focus related entries in main.c for the IXUS285.

stubs_entry_2.S

Code: [Select]

NHSTUB(time, 0x006B9180)0xff86c2d8 is a different routine. From a simple disassembly, code above address 0xff8642f4 (start of "RAM code" in the below stubs_entry.S section) is relocated to a lower RAM address.

Code: [Select]

// Detected address ranges:
// ROM      0xff010000 - 0xffffffff (16711680 bytes)
// RAM code 0x006b1000 - 0x006e2d30 copied from 0xff8642f4 ( 204080 bytes)
// RAM data 0x00001900 - 0x000189bc copied from 0xff84d238 (  94396 bytes)

... and Phil fixed the rest while I was writing this.

Thanks guys.
Attached is a test build.
