Hi everyone,
Please help:
I have several 89LPC936 with similar problems, namely, when I tried programming ICP (via EMP900 & PAB900), I get Sector 7 write error if I try to write into ISP area.
I included LPC_ISP_16K_V03.a51 in my compilation and set erase sectors 0 to 7.
Even when I managed to program, I was only able to read signature via ISP but when I tried programming via ISP and follow it by a read signature, it fails (even after start bootloader invoked).
I read on line that although 0x3F is used as bootvec and bootstat is set as 0x01, the notouch examples set the boot vector to be 0x1f00. Reading the LPC936 spec pg. 24 Fig 8 suggests that ISP code is at 1FFFh.
What should I do to get ISP working.
Thanks
Regards
