My motherboard -has the model number "CMA102-32M-990526-01". These are both fairly old, -and may not reflect current design. In particular, I can see from the -Cogent web site that the CMA286 has been significantly redesigned - it -now has on board RAM (4M), ethernet 10baseT PHY (on SCC2), 2 serial ports -(SMC1 and SMC2), and 48pin DIN for the FEC (if present i.e. MPC860T), and -also the EPROM is 512K. - -My CMA286-60 has none of this, and only 128K EPROM. In addition, the CPU -clock is listed as 66MHz, whereas mine is 33.333MHz. - -Clocks ------- - -Quote from my "CMA286 MPC860/821 User's Manual": - -"When setting up the Periodic Interrupt Timer (PIT), be aware that the -CMA286 places the MPC860/821 in PLL X1 Mode. This means that we feed -a 25MHz clock directly into the MPC860/821. This mode sets the divisor -for the PIT to be 512. In addition, the Time Base Register (TMB) -divisor is set to 16." - -I interpreted this information to mean that EXTCLK is 25MHz and that at -power on reset, MODCK1=1 and MODCK2=0, which selects EXTCLK as the -source for OSCCLK and PITRTCLK, sets RTDIV to 512 and sets MF (the -multiplication factor) to 1 (I assume this is what they mean by X1 -mode above). MF=1 means the cpus internal clock runs at the same -rate as EXTCLK i.e. 25MHz. - -Furthermore, since SCCR[TBS] (the Time Base Source selector bit in the -System Clock and Reset Control register) is set in the cpu initialisation -code, the TMBCLK source is forced to be GCLK2 and the TMBCLK prescale is -forced to be 16. This results in TMBCLK=1562500. - -One problem - since PITRTCLK source is EXTCLK (25Mhz) and RTDIV is 512, -PITRTCLK will be 48828.125 (huh?). Another quote from the MPC860 Users -Manual: - -"When used by the real-time clock (RTC), the PITRTCLK source is first -divided as determined by RTDIV, and then divided in the RTC circuits by -either 8192 or 9600. Therefore, in order for the RTC to count in -seconds, the clock source must satisfy: - - (EXTCLK or OSCM) / [(4 or 512) x (8192 or 9600)] = 1 - -The RTC will operate with other frequencies, but it will not count in -units of seconds." - -Therefore, the internal RTC of the MPC860 is not going to count in -seconds, so we must use the motherboard RTC (if we need a RTC). - -I presume this means that they do not provide a fixed oscillator for -OSCM. The code in get_gclk_freq() assumes PITRTCLK source is OSCM, -RTDIV is 4, and that OSCM/4 is 8192 (i.e. a ~32KHz oscillator). Since -the CMA286-60 doesn't have this (at least mine doesn't) we can't use -the code in get_gclk_freq(). - -Finally, it appears that the internal clock in my CMA286-60 is actually -33.333MHz.

When programming the CMA302, the FLASH devices appear as 2 - * banks of interleaved, 32-bit wide FLASH. Each 32-bit word consists of four - * 28F008S5 devices. The first bank is accessed when the word address is even, - * while the second bank is accessed when the word address is odd. This must - * be taken into account when programming the desired word. Also, when locking - * blocks, software must lock both banks. The CMA302 does not directly support - * byte writing. Programming and/or erasing individual bytes is done with - * selective use of the Write Command. By not placing the Write Command value - * on a particular byte lane, that byte will not be written with the following - * Write Data. Also, remember that within a byte lane (i.e. D0-7), there are - * two 28F008S5 devices, one for each bank or every other word. - * - * End quote. - * - * Each 28F008S5 is 8Mbit, with 8 bit wide data. i.e. each is 1Mbyte. The - * chips are arranged on the CMA302 in multiples of two banks, each bank having - * 4 chips. Each bank must be accessed as a single 32 bit wide device (i.e. - * aligned on a 32 bit boundary), with each byte lane within the 32 bits (0-3) - * going to each of the 4 chips and the word address selecting the bank, even - * being the low bank and odd the high bank. For 64bit reads, both banks are - * read simultaneously with the second bank on byte lanes 4-7. Each 28F008S5 - * consists of 16 64Kbyte "block"s. Before programming a byte, the block that - * the byte resides within must be erased. So if you want to program contiguous - * memory locations, you must erase all 8 chips at the same time. i.e. the - * flash on the CMA302 can be viewed as a number of 512Kbyte blocks. - * - * Note: I am going to treat banks as 8 Mbytes (1Meg of 64bit words), whereas - * the example code treats them as a pair of interleaved 1 Mbyte x 32bit banks. - */ - -typedef unsigned long c302f_word_t;

The following - * 3 x 32 Mbyte areas (0x2000000-0x3FFFFFF, 0x4000000-0x5FFFFFF and - * 0x6000000-0x7FFFFFF) are general I/O "slots" (slots 1, 2 and 3). - * Most other motherboard devices have registers mapped into the area - * 0xE000000-0xFFFFFFF (Motherboard I/O slot?). The area 0x8000000-0xDFFFFFF - * is free for whatever. - * - * The location of the motherboard address space in the physical address space - * of the cpu is given by CMA_MB_BASE.
