Re: IPC Hammer
I looked into this and fixed it today. So it will work in the next version.kur4o wrote:I also tested the ipchammer, some functions work, others not, On read properties it stops, when there is a negative 7f response. Maybe some exception can be added, so info from non fully supported ipcs still can be read.

Re: IPC Hammer
Nice to see you got it to read out correctly. I had to go back and learn to calculate the checksums again. I'm starting to get interested in messing with the clusters and updating IPChammer again. Thanks for the script to read the clusters. Do you have any info on how to write the scripts? like what...

Re: IPC Hammer
If I remember correctly you have to do 16 bit big endian sum and then 2’s complement.

Re: IPC Hammer
I’ll have to look for the checksum math. The range of 8000-bfff would be used for external access. I don’t think the clusters use the external bus. All the boot loader is in 0-3fff. The calibration should be in 4000-7fff.

Re: IPC Hammer
The os checksum should be from 0x18002 to the last byte before the 0xC3A5 at the end of the os. If you change the 0xC3A5 at the end of the os and make a bin with just the os the test checksum button in ipchammer should work to calculate the checksum.

Re: IPC Hammer
I use minimon from Infineon with a usb to serial adapter. Fixed until broken on YouTube has videos on how to do it.

Re: IPC Hammer
Looking at your file. It looks like you dumped the bootloader and calibration. The bootloader starts at 0x0000 and the calibration starts at 0x4000. The OS starts at 0x18000 and ends at 0x1FFFF. I believe that the ram starts at 0xC000.

You can get it at https://github.com/mikebb203/IPC-Hammer. It won’t program a trailblazer yet.

Re: JTAG(ish) access to IPC V850
That would be great. No worries about quality. I still need to learn all the steps to design my own prints.
