Convert Banked GCC S1 to linear S2 record

ServoPump — Thu, 29 Oct 2020 08:43:44 GMT

Hi,

I'm using GCC tools for the NE64 chip that generate S1 record that starts at 0x4000 and ends at 0xFFFF. The PPAGE register is set to 0x3D to get a linear flash space.

The GCC memory.x file is as follows:

Code:

MEMORY{  ioports (!x)  : org = 0x0000, l = 0x0400  eeprom  (!i)  : org = 0x, l = 0x  data    (rwx) : org = 0x3200, l = 0x0E00  text    (rx)  : org = 0x4000, l = 0xB800  vectors (rx)  : org = 0xFF80, l = 0x0080}PROVIDE (_stack = 0x4000);vectors_addr = 0xFF80;

I have tried for 3 day using SRecCvt-GUI to generate and program the NE64 with no luck.

Has anyone run into this problem?

Thanks in advanve for your help

Sreccvt (and of course its GUI) is useless when it comes to converting nonpaged addresses $8000-$BFFF. You say that PPAGE is set to 3D. But sreccvt doesn't know that $8000-$BFFF belong to page 3D and there's no way to tell sreccvt where to move $8000-$BFFF to.

To solve the issue you could exlude 8000-bfff from your "linear" memory map. But this is probably not what you want. So you need to extract 8000-BFFF S-records to separate file and shift these to proper "page" using sreccvt with -of switch. For example to move 8000-bfff to page 3C use -of switch argument set to (page=3C * 0x4000 - 0x8000):

sreccvt -m 8000 FFFFF 32 -of E8000 -o sfile8000bfff_OUT sfile8000bfff_IN

Then you should put sfile8000bfff_out back into your S-file. This converted S-file will be compatible with sreccvt and its GUI :smileyhappy:.

grep may help moving 8000-bfff to separat file.

you could try logphy convertor from P&E. Select custom to define the PPAGE=$3D for $8000 area
