Using: Codewarrior 3.0 on HCS12DG128 How do I map the EEPROM with Codewarrior? The only way I know of is to set the INITEE register manually. If I do that, everything will be fine except that the memory will then be erased at startup, which I don't want. I have wr

Hello, I would like to configure my 9s12dp256 to use register : 0-3FF, EEPROM 400-13FF, RAM 1400- 43FF Is it possible? If yes, i don't find the correct value of INITEE and INITRM An other question : if RAM is > at $4000 wich is a fixed flashed page, what append? All of these adress questions are not clear for me.... Thank you

Hello all, I am trying to interface my HC12 with an I2C EEPROM and I am having trouble performing a write to the EEPROM (Model No. M24C02) The worst part is that the in circuit debugger that I am using (ICD12Z from P&E) seems to be doing something really weird whe

Gilles, Cheers for your service. I had been critical overnight of the Metrowerks service pages, but as usual this forum has proved worth its weight. The algorithm plugged in a ran nicely. My alternate solution from last post last night didn't work and I had resorted to copying the table with a runtime function into EEPROM when it detected the

I'm working with the MC912D60A microcontroller. I just realized the access for EEPROM earasing and programming. So far everything works fine. It's just that I don't understand the idea of the SHADOW byte. Form the specs I read it is located at adress 0x0FC0- 0x0FC1. Actually these ar

I have been trying to write to the EEPROM on the HC9S12XD256 processor and have been having problems getting it to write. The OSC is 12 MHz, but we run the PLL to bring it up to 48 MHz. Our EDIV is set to 60 (with no PRDIV8). The following code is on FreeScale CodeWarrior 4.7. Is there something blatently obvious that I'm doing wrong? (I know I need timeouts instead of infinite whil...

Hello, I write some values in the eeprom of 9s12dt128. Before doing a hard reset (power off) if i read the content at 0x800 it is correct. I do the hard reset and i follow this code with the debugger : for(;;) { /* forever: initialize the program; call the root-procedure */ if (!(_startupData.flags&STARTUP_FLAGS_NOT_INIT_SP)) { /* initialize the stack pointer */ ...

Hello All, iSYSTEM tells me that there is a bug at least in the 9S12D64 and 9S12DT128 (not in the DP256) so that it's not possbile to write EEPROM directly (without "monitor" code) via the BDM interface in special mode. The problem arises when accessi

I have been using a set of routines for over a year to read and write to the internal EEPROM memory of a 68HC912DG128A processor. The routines have worked without incident. During the development phase of these routines I thought it necessary to disable interrupts before accessing t

Hello Has anyone figured out how to avoid having Codewarrior 3 erase the eeprom every time one flashes the code with the ICD-12 target module? With version 2, one could achieve this by editing "P&E_ICD_erase_unsecure_hcs12.cmd", but with version 3 there is a new mech

I'm having a real challenge trying to sort out the code for EEPROM setup and programming for the HC912D60. I know how the HC11E20 is set up, but I see conflicting methods for the HC912D60 and no example code. In some examples (B32, A4) they set it up like the HC11

Dear Everyone, I am working with the MC9S12XS128 MCU. This MCU doesnt have the EEPROM but it has D-Flash. And I studied the data sheet for MC9S12XEP100 refference manual and the application note AN3490.pdf. Which says MC9S12XEP100 has the optional Emulated EERPOM which can be done by carefully partioning the availabe D-Flash. And the document says it has many advantages like .. ...

Hello, I need to store four strings into non-volatile storage. One string will be 15 chars in length and the other three will be 10 chars in length. The strings may be written less that 10 times in the device's lifetime, but will be read possibly thousands of times. It is very important that the strings remain in memory if the power is lost! Is EEPROM the right place for this? I am working w...
