P1025 QUICC engine

[alexandermaslov]

Where can I download ucode for P1025 QUICC engine? Is p1021 ucode compatible with p1025 QUICC engine?

Hi! I am trying to write a qiucc engine driver for p1025. My driver must not use dynamic memory allocation. I use NetComm Software Realease GA 4.4. The problem: 1) My soft call t_Handle QE_Config(t_QeParam *p_QeParam)

2) call QE_LoadUCodeToRam(tHandle, uint32_t*,uint32_t, uint64_t). ucode is taken from iram_Type_D_r1.h.

3) call t_Error QE_Init(t_Handle). The programm hangs in this function. It can't issue command to quicc engine, i.e. succesful return from QE_IssueCmd(p_Qe, e_QE_CMD_PROTOCOL_UNSPECIFIED, (uint32_t) p_Qe->p_QeTimerTables - pramBase).

What is the problem?

Hi Alexander,

I can not answer your question directly, but our company can offer you help on this. We have ability to develop custom microcodes for QuiccEngine and see from the QuiccEngine side what could be the problem microcode is not responding to your commands.

best regards,
