A.7.3. Arria 10 SoC FPGA Configuration Sequence Through FPGA Manager
The FPGA Manager in the HPS has the capability to execute an initial FPGA configuration using the full or early I/O release flow.
The steps below detail the programming of the FPGA Manager to initiate configuration.
- Read the f2s_msel[2:0] field in the imgcfg_stat register to verify that the configuration mode is the passive fast (000) or passive slow (001).
- Write the cfgwidth bit of the imgcfg_ctrl_02 register in the FPGA manager to match the characteristics of the configuration image. For full, standard configuration, the cfgwidth bit must be set to 1. You can only initiate a full, standard configuration in 32-bit passive parallel mode.
- Configure the cdratio field. The cdratio is a function of the datawidth and whether the POF in encrypted or compressed. This information should be provided through the Intel® Quartus® Prime configuration. For example,if cfgwidth is 32-bits and the POF is compressed, you must program the cdratio field to 0x8. If the POF is encrypted, then program the cdratio to 0x4.
- Ensure there are no other external devices interfering with the FPGA programming. Poll the f2s_nconfig_pin and f2s_nstatus_pin bits from the imgcfg_stat register until they are both 1.
- Program the following bits to deassert signal drives from the HPS before overriding the signals.
- s2f_nce =1 in the imgcfg_ctrl_01 register
- s2f_pr_request= 0 in the imgcfg_ctrl_01 register
- en_cfg_ctrl= 0 in the imgcfg_ctrl_02 register
- s2_nconfig = 1 in the imgcfg_ctrl_00 register
- s2f_nstatus_oe = 0 in the imgcfg_ctrl_00 register
- s2f_condone_oe = 0 imgcfg_ctrl_00 register
- Enable overrides for the DATA, DCLK, nCE, PR_REQUEST and nCONFIG signals.
- s2f_nenable_config = 0 in the imgcfg_ctrl_01 register
- s2f_nenable_nconfig = 0 in the imgcfg_ctrl_00 register
- Disable overrides for the nSTATUS and CONF_DONE signals.
- s2f_nenable_nstatus = 1 in the imgcfg_ctrl_00 register
- s2f_nenable_condone = 1 in the imgcfg_ctrl_00 register
- Assert the chip select signal.
- s2f_nce=0 in the imgcfg_ctrl_01 register
- Repeat step 4. Ensure there are no other external devices interfering with the FPGA programming. Poll the f2s_nconfig_pin and f2s_nstatus_pin bits from the imgcfg_stat register until they are both 1.
- Reset the configuration.
- Write a 0 to the s2f_nconfig bit in the imgcfg_ctrl_00 register.
- Poll the f2s_nstatus_pin bit in the imgcfg_stat register until it is clear.
- Write a 1 to the s2f_nconfig bit in the imgcfg_ctrl_00 register.
- Poll the f2s_nstatus_pin bit in the imgcfg_stat register until it is set. In addition, read and confirm the f2s_condone_pin is clear and the f2s_condone_oe is set in the imgcfg_stat register.
- Enable DCLK and the DATA path by setting the en_cfg_ctrl bit in the imgcfg_ctrl_02 register.
- Write the bitstream data to the img_data_w register. When sending the bitstream data, you can periodically read and confirm that the f2s_nstatus_pin bit is set in the imgcfg_stat register. If it is not set, configuration has failed and you must restart with step 1.
- When you have completed writing the data, continuously poll the f2s_condone_pin bit in the imgcfg_stat register until it reads as 1. When this bit is 1, it indicates configuration has completed. If the routine times out with f2s_nstatus_pin=0, configuration has failed and you must restart from step 1.
- Write the dclkcnt register with 0xF and continuously poll until the dclkcntstat register reads as 0x0. A minimum of 2 DCLK cycles are needed after the CONFIG_DONE assertion for initialization to start.
- Wait for the initialization sequence to complete. Poll the f2s_usermode bit in the imgcfg_stat register until it reads as 1.
- Disable the DATA path and DCLK by clearing the en_cfg_ctrl bit in the imgcfg_ctrl_02 register.
- Disable the chip select. Set the s2f_nce bit in the imgcfg_ctrl_01 register.
- Disable overrides to the nCONFIG, DATA and DCLK signals.
- s2f_nenable_config=1
- s2f_nenable_nconfig=1
- Check that user mode is enabled and the configuration is done by checking that the bits below have the following values:
- f2s_usermode=1 in the imgcfg_stat register
- f2s_nstatus_pin=1 in the imgcfg_stat register
- f2s_condone_pin=1 in the imgcfg_stat register
