Thank you very much,

Your compiler is set to banked model witch allow only banked code and
not banked data.
Data must be in non banked memory.

Try to set compiler to large memory model.

Zadeva: [68HC12] Codewarrior & flash data problem
I sent this question days ago and I don't receive any answer. Now I will
try to explain the problem better.

I'm new in HCS12 programming and after successful tests with Codewarrior
Processor Expert using SPI, SCI, timers, etc., now I'm trying to store
some data in flash. I thought that Codewarrior Bean "Internal Flash"
would help, but I got some problems.

For example, if I read some data from 0x388000 (Flash1, Page 0x38)
calling IFsh1_GetPage(0x388000) got the code stored in Page 0x30 from
where program is running.

Otherwise, if I trace into the process, when IFsh1_GetPage calls
SelectBank(dword Addr) PPAGE is changed to 0x38 and program hangs due
0xFFFF execution in erased flash.

Any help will be appreciated. Jordi Costa --------------------

I sent this question days ago and I don't receive any answer. Now I will try to explain the problem better.

I'm new in HCS12 programming and after successful tests with Codewarrior Processor Expert using SPI, SCI, timers, etc., now I'm trying to store some data in flash. I thought that Codewarrior Bean "Internal Flash" would help, but I got some problems.

For example, if I read some data from 0x388000 (Flash1, Page 0x38) calling IFsh1_GetPage(0x388000) got the code stored in Page 0x30 from where program is running.

Otherwise, if I trace into the process, when IFsh1_GetPage calls SelectBank(dword Addr) PPAGE is changed to 0x38 and program hangs due 0xFFFF execution in erased flash.

Any help will be appreciated. Jordi Costa
