LPC9xx/LPC9xxx / To write LPC901 flash with IAP
« on: April 02, 2009, 01:16:18 pm »
Hi. I am developing a device, and I am using the LPC901. I need record some data in the flash memory of MCU, but I did not find the command lines for this. The compiler wich I am using is uVision3, of the Keil.

It is very important to me, I am waiting response. Thanks in advance!!!

LPC9xx/LPC9xxx / Mysterious problem with ISP-TO-ICP Bridge
« on: March 19, 2009, 05:27:01 am »
Hello I am trying to record the 89LPC901 with the way ISP-TO-PCI Bridge, using a 89LPC936 with the code version 1.6, and FlashMagic 4.61. I am not using the card MBC900 as described in AN10258. In place of the plate put a MAX232 to convert TTL to RS-232. The problem is: the vast majority of times, I can not run the recording of the chip 901. The same is on the board and is connected to the "recorder" for a POD with needles. When connecting the card to the recorder, the LED of the 901 circuit lights, indicating that the VDD supply of the recorder is activated, and in these cases, the FlashMagic indicates that the ID does not match with the chip set, and recording is not success. However, sometimes the LED of the LPC901 circuit does not lights, indicating absence of initial VDD, and in these cases, the code is written correctly, can even do calculations of CRC, and so on. I wonder if you have any idea what this may be because the problem does not appear to be in communication between PC-> 89LPC936, but between LPC936-> LPC901.
I await reply, thank you.
