Could anyone help me to run the IAP commands on KEIL MCB2100 (LPC2129)? I am working with the ARM RVDS tools (& RV ICE) and tried to run a small sample calling the IAP commands (program runs from iRAM). Most time I get a "memory access violation" several seconds after calling the IAP commands. Sometimes the first IAP command (code 50) runs ok but I did never saw a guilty write command. I tried it also with cclk = 12MHz. Do I have to do additional initialisation? I have reserved 16 bytes on top of Stack. best regards Stefan This is my source static void PLL_Init(void) { // Fosc = 12.000.000 MHz PLLCON = 1; // enable PLL PLLCFG = 0x24; // M=5 and P=2 -> Cclk = 60.000.000 MHz PLLFEED = 0xAA; // PLL Feed Sequence PLLFEED = 0x55; // PLL Feed Sequence while (!(PLLSTAT & 0x400)); // wait for the PLL to be locked PLLCON = 3; // enable and connect PLL PLLFEED = 0xAA; // PLL Feed Sequence PLLFEED = 0x55; // PLL Feed Sequence VPBDIV = 0; // Pclk = 15.000.000 MHz } static void PLL_Off(void) { // Fosc = 12.000.000 MHz PLLCON = 0; // disable PLL cclk = Fosc VPBDIV = 1; // Pclk = cclk } void savesetup(struct SETUP *setup){ typedef void (*IAP)(unsigned int [],unsigned int[]); unsigned int command[5]; unsigned int result[2]; IAP iap_entry; // PLL_Off(); //__ARMLIB_disableIRQ(); iap_entry=(IAP) IAP_LOCATION; // prepare to erase command[0]P; command[1]; /* start sector */ command[2]; /* end sector */ iap_entry(command, result); if (result[0] != 0) goto error; // erase command[0]R; command[1]; /* start sector */ command[2]; /* end sector */ command[3]`000; /* System Clock cclk in KHz */ sendstr ("\nnow erase"); iap_entry(command, result); /* erase the block */ if (result[0] != 0) goto error; // prepare to program iap_entry=(IAP) IAP_LOCATION; command[0]P; command[1]; /* start sector */ command[2]; /* stop sector */ sendstr ("\nnow prepair to program"); iap_entry(command, result); if (result[0] != 0) goto error; // program command[0]Q; command[1]=0x1C000; /* destination address */ command[2]=(int)setup; /* source RAM adress */ command[3]Q2; /* number of Bytes*/ command[4]`000; /* system clock cclk in KHz */ sendstr ("\nnow program"); iap_entry(command, result); if (result[0] != 0) goto error; //__ARMLIB_enableIRQ(); return; error: sendstr ("\nFlash Access error"); //__ARMLIB_enableIRQ(); } int main (void) { unsigned int ui_cnt; struct SETUP setup; struct SETUP * nonvolatile; nonvolatile= (struct SETUP*) 0x1C000; /* Points to page 14 in Flash (LPC2106)*/ PLL_Init(); // PLL_Off(); /* Init General Purpose I/O GPIO */ IOCLR1 = 0xFFFFFFFF; IODIR1 = 0x00FF0000; /* Port 1[23..16] is Output LEDs */ init_serial(); /* Initialize Serial Interface */ sendstr ("\nIAP Test"); while (1) { /* Loop forever */ setup=*nonvolatile; /* read ROM to RAM */ sendstr ("\nsetup.ui_CH_ZS_Value = 0x"); sendhex((setup.ui_CH_ZS_Value[0] >> 28) & 0x0F); sendhex((setup.ui_CH_ZS_Value[0] >> 24) & 0x0F); sendhex((setup.ui_CH_ZS_Value[0] >> 20) & 0x0F); sendhex((setup.ui_CH_ZS_Value[0] >> 16) & 0x0F); sendhex((setup.ui_CH_ZS_Value[0] >> 12) & 0x0F); sendhex((setup.ui_CH_ZS_Value[0] >> 8) & 0x0F); sendhex((setup.ui_CH_ZS_Value[0] >> 4) & 0x0F); sendhex(setup.ui_CH_ZS_Value[0] & 0x0F); setup.ui_CH_ZS_Value[0]++; /*modify for test */ setup.ui_CH_FS_Value[0]++; savesetup (&setup); } |

I have some problems with the IAP as well. After upgrading to version 1.63 bootloader (one is a LPC 2124 the other a LPC 2129) the behavior is predictable but not what should happen. I do 4 steps: 1. prepare 2. erase 3. prepare 4. coppy RAM to flash. Steps 1. to 3. show as Status Code CMD_SUCCESS but definetly erase does not work. Step 4. gives back 9 SECTOR_NOT_PREPARED_FOR_WRITE_OPERATION. Any help would be appreciated.

Make sure you are in thumb mode before calling any IAP code (as it is implemented in thumb).

To philips_apps: There is an error in the LPC2114/2124/2212/2214 USER MANUAL(date 2004-05-03) - On page 33 figure 2 it shows the LPC 2124 in the block of devices with 128 kB flash!! It has 256 kB. In my example Sector 14 and address 0x1C000 didn't fit for the LPC 2124 doing IAP and resulted in Status Code 9 SECTOR_NOT_PREPARED_FOR_WRITE_OPERATION. Helmut |
