Hi,
I'm trying to use the I2C controller to communicate with my own I2C peripheral. First, I was trying to build the tb by including the I2C EEPROM (I've followed the README instructions). The problem is that, when using the example program for I2C, the RTL simulation gets stuck at the first write operation. Moreover, SDA and SCL signals never toggle during RTL simulation.

Do you have an example program I can use to make I2C work? I guess I need to make some initialization..

Hi, 

I'm trying to preload the program in L2 cache but i'm unable to trace which addresses goes into which memory
so far what i got tracing is the hello world example:

/tb_pulp/i_dut/soc_domain_i/pulp_soc_i/l2_ram_i/bank_sram24k_scm8k_pri0_i/cut_0/MEM
addresses in stimuli file from 1C000000 - 1C001030 go in this memory

/tb_pulp/i_dut/soc_domain_i/pulp_soc_i/l2_ram_i/bank_sram_pri1_i/MEM
 address in stimuli file from 1C008000 - 1C00AF80 go in this memory

but i have no idea where the rest goes. 
Question 1: is the mapping mentioned anywhere in the hdl files?
Question 2: I've not been able to build the documents in ipstools due to python libraries errors is there a pdf or a latex version i can get anywhere else online?

Thanks,
Bassma

Hello,

I have build a FPGA project of pulpissimo. How do I download the program to my CPU with JTAG interface?

Thanks.

Dear PULP user / PULP team member,

For a while now, PULP has been gaining momentum and as a result, we decided to start a forum. This has been done with the intention to increase the visibility of PULP's support. Since the support has been currently provided via pulp-info and dedicated GitHub pages, it is not easily searchable. Another reason why we decided to start a forum is the intention to build a community around PULP and possibly promote frequently engaged users to moderators. Based on the number of support requests received via pulp-info we decided not to create dedicated subforums, but we do not exclude that this might happen in the future.
