Hello, I am developing a bootloader for c8051f580 from Silabs. I follow the AN112 and AN533. I use the signature for check that app is well flashed. I put that signature at 1F1FEh so the Bank 3. I compile, link and download the omf to the chip and everything is ok. But when i generate the hex file i see that the signature is at F1FEh address. I know the problem with intel-hex about 64kB limit, so i generate the hex with ohx51 and option h386 and merge32k.
Someone could give light to my problem?...
My sequence is this:
C51==DB OE BR INTVECTOR(0x0A00) INTERVAL(3) Large
BL51 == BANKING == RS(256) PL(68) PW(78) CODE(0x0A00) BANKAREA(8000H,0FFFFH) BANK3(?CO?SIGNATURE (0xF1FE))
Using LX51 RESERVE (C:0x0000-C:0x09FF) SEGMENTS ( ?CO?SIGNATURE (B3:0xF1FE)) BANKAREA(8000H,0FFFFH)
OHX51.exe h386 MERGE32K
My memory map is something like that:
* * * * * * * C O D E M E M O R Y * * * * * * * 0000H 0A00H *** GAP *** CODE 0A00H 0003H ABSOLUTE CODE 0A03H 0003H ABSOLUTE 0A06H 0003H *** GAP *** CODE 0A09H 0003H ABSOLUTE CODE 0A0CH 0005H UNIT ?PR?I2C_NACK?SOF .... CODE 9B0AH 0007H UNIT ?PR?GENERASTOP?I2C CODE 9B11H 0007H UNIT ?PR?I2C_INIT?SOFTI2C CODE 9B18H 0004H UNIT ?PR?WATCHDOG_REFRESH?TIME >> RS * * * * * * * C O D E B A N K 3 * * * * * * * 0000H F1FEH *** GAP *** BANK3 F1FEH 0002H UNIT ?CO?SIGNATURE
I think the problem is when i generate the hex, that i need to do something more...
Thanks for the time.
the search there stinks to high heaven, I suggest you post your question at www.cygnal.org/.../Ultimate.cgi (which also stinks, quite often times out, be patient and try again till you succeed) and someone will remember posting about this and repeat the answer.

Ok Erik, thank you very much
I just found the problem. I had to code banking, because my program exceeded 32kb of the common bank so i was writing in the bank 1, just put some code in the bank 1 using code banking and use LX51 and OHX51. I also have to check the startup.a51 because some project use differents type of file. I have to compare with the one that is included with the code banking example.
Thank you very much.
